Catalase is an enzyme that catalyses the breakdown of hydrogen peroxide into water and oxygen gas.
A student designed an experiment to investigate the effect of hydrogen peroxide concentration on the rate of this catalase-controlled reaction.
The student had access to:
The first step of the student's plan is:
Step 1. Add 2 cm3 of the pH 7 buffer solution to each of the five boiling tubes.
Describe the next two steps that should be in this plan to obtain valid results for this investigation.
