Experiment on How Increasing Reactant Concentration Affects Reaction Rate

The video discusses a required practical activity from the chemistry specification, which is an experiment to investigate how increasing the concentration of a reactant affects the rate of the reaction by observing a precipitate. The video explains a possible hypothesis for this experiment and the steps to be taken to test that hypothesis. It also highlights the apparatus used in the experiment, how to measure the rate of reaction, and how to calculate the mean rate. The video concludes by discussing how to plot the results on a scatter graph and how to draw the line of best fit to conclude that the rate of reaction is proportional to the concentration of the acid.
