Research Question:
How does the concentration of hydrogen peroxide affect the time (s) it takes the enzyme catalase to decompose it into water and oxygen gas?
Variables:
Dependent:
- Time (in seconds) taken for the decomposition reaction to be complete.
- Measured using a stopwatch
Independent:
- Molar concentration (mol/L) of hydrogen peroxide (H2O2)
- Solutions will be increased in concentration from 1 mol/L to 1.25 mol/L, to 1.5 mol/L, to 1.75 mol/L, to 2 mol/L.
