Did you know?
Yes. Hydrogen peroxide is acid as it has a pH of 6.2. However, the pH value depends upon the concentration as well as the temperature of the solution. At the temperature of about 25°C, depending upon the concentration of hydrogen peroxide in the solution, the ph value ranges from 4.2 to 7. See more Weak acids have a low value of acid dissociation constant (Ka). In the case of hydrogen peroxide, the Ka value is about 1.55 X 10-12 at 298 K indicating that it is a weak acid. Further, … See more pH is the quantitative measure to gauge the acidity or basicity of a solution.
