5 litres of 1x10^-2 Dodecylamin has been diluted to 1x10^-5M by adding accurate amount of water from the tap. To calculate required water amount mathematical equations given below : C1V1=C2V2 10^-2M x V1 =10^-5M x 1,000 mL V1 = 10^-5/10^-2 = 10^-3 M = 1,000 mL Here C1,C2; are the first and second concentrations of solution V1 and V2 ; are the required and current volumes. The impeller turned on and DDA, and tap water left to be mixed properly with water for 2 minutes. Approximately 150 grams of quartz added into the solution. Froth should not be stuck in the area where overflow speed is relatively lower and this was done by using a spatula. Attention paid to make froth collection almost waterless. The collection time intervals …show more content…

To compute rho, the program GSC threshold.m denes two non-linear functions root2d and root2r as in Equation (15) and (16) of [1]. Each of these functions represents a system of non-linear equations in two variables. The program numerically solves these two by two systems of non-linear equations by using the inbuilt MatLab function f-solve. Since the probabilities, PNi are numerical solution computed by MatLab these values can be very very small numbers. To avoid these artifacts, the program replaces values of rho less than l_t by

Use your results in Data Table 2 to support your answer.
The actual data is the result on our experiment vs theoretical, which is based on the calculations above. I have also learned to pay more attention to draining out all of the product completely before continuing to test the experiment, as any small drop of contaminant can veer our results into a different
