Question

How is the concentration of hydroxide ions (OH–) affected when excess base is dissolved in a solution of sodium hydroxide ?​

Answer 1

Answer:

The concentration of (OH−) Hydroxide ions increases when the excessive base is added to the solution of Sodium Hydroxide as the base itself dissociates to give out OH− ions which increases their concentration per unit volume..

Answer 2

$\huge \sf {\orange {\underline {\pink{\underline{Answer :-}}}}}$

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.
