Question

How is the concentration of hydroxide ions affected when a solution of an base is diluted?

Answer 1

$\huge \textbf{Dilution}$

→Addition of water to acid or base is caleed dilution.

The concentration of hydroxide ions will increase when excess base is dissolved in a solution of sodium hydroxide, but it happens to a limited extent only after which the concentration becomes almost constant.
