Web(apparent pH) is affected by hydrogen peroxide concentration. The decrease of stability at lower pH is not normally large, but at higher pH, the stability deteriorates very rapidly, and alkaline hydrogen peroxide may be very unstable. Contamination ofydrogen peroxide by acids and particularly alkalis must therefore be avoided.
