Question

In a solution, concentration of hydrogen ion is
1x10# gm mole L". Find pH of solution.
Tell whether solution is acidic or alkaline?​

Answer 1

pH=−log[H +]

5.4=−log[H + ]

[H+]=antilog(−5.4)=3.98×10−6

Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter. Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral.

Thus, small changes in pH represent large changes in the concentrations of hydrogen ions. Pure water is neutral. It is neither acidic nor basic, and has a pH of 7.0. Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline.
