Question

The original experiment, "Factors Affecting the Rate of Reaction," examines how changes in the concentration of sodium thiosulfate impact the rate of reaction (Huddart, 2018). In the experiment, 10 mL of 0.25M sodium thiosulfate (Na2S2O3) and 5 mL of hydrochloric acid (HCl) were initially mixed with 35mL of water. Then the amount of time it took for the mixture to disappear from the cross was recorded to quantify the rate of reaction. Then differing concentrations of sodium thiosulfate diluted with different volume of water was used to compare the rate of reaction with the original concentration (15:30, 25:20, 35:10, 40:5). The experiment includes an independent variable, sodium thiosulfate concentration, and a dependent variable, the time it takes for the cross to disappear.
