Question

Compute the pH of a solution at 25oC (to the nearest integer) which is twice as alkaline as pure water.

Open in App
Solution

The solution is twice as alkaline as pure water.
For pure water, the hydroxide ion concentration is 1×107
M. Hence, the hydroxide ion concentration of the solution is 2×107.
Calculate the pOH of the solution.
pOH=log[OH]=log(2×107)=6.7
Now calculate the pH of the solution.
pH=14pOH=146.7=7.3
