Enzyme+Inhibition

Enzyme Inhibition
we tested enzyme inhibition by adding various concentrations of Copper II Sulfate (CuSO4) to the H2O2. we always used 8mL of H2O2 and accounted for the other 2mL by adding H2O. when we started adding the CuSO4, we would use 8mL of H2O2, but different amounts of H2O depending on how much CuSO4 was added: so if we added .5mL of CuSo4 to the 8mL of H2O2, we would only add 1.5mL of H2O to always keep the solutions at 80% H2O2 and to keep the total solution volume at 10mL. the baseline data was collected the first day of the experiment, the 5% CuSo4 solution trial was conducted on the 3rd day of the experiment and concentrations of 10% - 20% were all collected on the fourth day.

20% CuSO4 H2O Temp 26.3C Pfister comment: Title = CuSO4? Also, I'm assuming the key is also supposed to have 0%, 5%, 10% and 15% CuSO4, not H2O2 since you were changing the concentration of the inhibiting chemical rather than the substrate...right?
