Question

hydrogen peroxide ionised as H2O2=H+ + HO2-. If pH of H2O2 is 5.91 the ionic product of H2O2 is​

Answer 1

Answer:

It depends upon a number of factors discussed below. But first, a few points on what pH means: pH is a logarithmic measure -- pH = log10 1/[H+]. Hence, if you mix equal parts of a pH 2 solution and pH 4 solution, you will not necessarily end up with a pH 3 solution -

Reason No. 1: According to the definition of pH, the pH 2 solution has 100 times the concentration of hydrogen ion [H+], not twice the concentration.

Reason No. 2: Both the pH 2 solution and pH 4 solution may contain "buffering agents" which dampen shifts in pH despite the addition of acids or bases.
