Abstract The purpose of the experiment was to test which antacid medicine was most effective in decreasing the acidity levels in the stomach. Titration experiments involving hydrochloric acid and sodium hydroxide were used to test different antacids to see which one needed the least amount of sodium hydroxide to turn the solution pink. The antacids that were being compared in this experiment were Alcalak, Alka-Seltzer and Medi-First. With the use of M1 x V1 = M2 x V2 the excess volume of hydrochloric acid was found in order to find the amount of hydrochloric acid volume neutralized out of the original 100 mL of hydrochloric acid. The results obtained for the volume neutralized by each antacid were 45.28 mL (Alcalak), 11.70 mL (Alka-Seltzer) …show more content…
Acid reflux is an extremely common health problem, affecting as many as 50 percent of the US population [1]. It's important to understand that acid reflux is not due to having too much acid in your stomach, but rather it's a condition related more commonly to hiatal hernia – a condition in which the acid comes out of your stomach, which is where it's designed to be confined to [1]. Another, problem that was found to be associated with high stomach acidity levels is heartburn. Heartburn pain is a direct result of irritation to the esophagus, which occurs when the lower esophageal sphincter (LES) is not functioning properly for some reason [2]. The LES is a muscular ring at the bottom of the esophagus that opens to let food into the stomach and then closes after the food has passed [2]. Its purpose is to prevent acidic stomach contents from entering the esophagus where it could burn the esophageal tissue [2]. When acid levels rise, the pH of the stomach drops, which causes the LES to shut itself as it senses the increased acidity …show more content…
Then, the antacid medicine, Medi-First, was placed in the 250 mL beaker. After, 5 drops of the indicator, phenolphthalein, was added to the 250 mL beaker with the addition of the magnetic stir bar. Second, the 250 mL beaker was placed on a magnetic stirrer on level 6 until the antacid was completely mixed in. Once the solution was prepared the beaker was placed on the base of the burette holder under the burette. Third, 32.7 mL of sodium hydroxide was poured into the 50 mL burette. Then the burette was released a little to gradually allow the sodium hydroxide into the beaker. Finally, the sodium hydroxide was stopped when the solution was completely pink and the amount of sodium hydroxide in the burette was recorded. To find the final amount of sodium hydroxide left, 50 mL must be subtracted from the final amount of sodium hydroxide in the burette. Then 32.7 mL subtracted by the final amount of sodium hydroxide will result in the total sodium hydroxide used until solution turned pink. This procedure was then repeated with the antacid Alcalak and Alka-Seltzer, which had different initial amounts of sodium
A hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.
Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made.
The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.
Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.
If you have a condition like this in your family, then you should really be aware and get checked by a gastroenterologist who specialize in this
Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated
The sodium citrate then dissociates in aqueous solution to form citrate ions that are able to form a buffer solution. This allows the Alka Seltzer to act as an antacid by neutralising the excess acid in the stomach, as H+ is used to form citric acid. The excess HCO3- ions in the aqueous mixture also act as a buffer which helps to reduce the acidity, further functioning as an antacid. (Shakhashiri B, 1989.) The aspirin in Alka Seltzer acts as an analgesic and also as an anti-inflammatory drug.
The Problem: How does temperature affect the dissolving time of an antacid tablet? Antacid tablets are medicines that help neutralize the acid in your stomach. Antacid tablets are made of numerous numbers of components, such as sodium bicarbonate (baking powder), magnesium hydroxide, critic acid, and many others. When Antacid tablets are placed in water, they undergo a chemical reaction, where the sodium bicarbonate breaks apart to make sodium and bicarbonate ions. When the bicarbonate ions collide with hydrogen ions, it produces carbonic acid.

Upon cooling, it was shaken until no bubbles were formed. 20 mL of each brand of soft drinks was titrated with NaOH solution. 3 drops of phenolphthalein was used as an indicator if it has already completely reacted. The acidity can then be calculated referring on the known concentration and volume of base; and the known volume of acid.
The drop rate was adjusted to 1 to 2 drops/second. 10.0 mL of the NaOH solution was allowed to drip away into a waste beaker. The exact volume of the sodium hydroxide solution used was determined.
The chemical equation for this experiment is hydrochloric acid + sodium thiosulphate + deionised water (ranging from 25ml to 0ml in 5ml intervals) sodium chloride + deionised water (ranging from 25ml to 0ml in 5ml intervals) + sulphur dioxide + sulphur. As a scientific equation, this would be written out as, NA2S2O3 + 2HCL + H2O (ranging from 25ml to 0ml in
That caused a new initial reading of NaOH on the burette (see Table1 & 2). The drops were caused because the burette was not tightened enough at the bottom to avoid it from being hard to release the basic solution for titrating the acid. The volume of the acid used for each titration was 25ml. The volume of the solution was then calculated by subtracting the initial volume from the final volume. We then calculated the average volume at each temperature.
(1-3) The disease demands prompt diagnosis, timely resuscitation and proper surgical management so as to reduce the morbidity and mortality. Surgery is the mainstay of emergency treatment of these life-threatening complications that are refractory to medical management. The ideal treatment for the perforation of duodenal ulcer has not yet been established. (4-5) Duodenal perforation is a very common and fatal complication in patients of chronic peptic ulcer symptoms with inadequate or no medical treatment.
Postoperative gastric axial rotation was detected in 6 patients all were in group (A).Those were diagnosed when suspected clinically by persistent vomiting, dysphagia, or refractory gastroesophageal reflux despite proton pump inhibitor treatment after the initial LSG, then it was confirmed by both upper gastrointestinal series and gastro endoscopy all were treated endoscopically ,all were functional stenosis no organic stricture was found.4 cases responded well to repeated dilatation using achalasia balloon dilator at an increasing pressure starting from 15-psi ,and the other 2 cases required stent deployment with a self-expandable metal stent for 3 weeks then stent was removed . No further intervention was needed in any of the patients. The case that was detected intraoperatively was in group B and so it was fixed with uneventful postoperative
