Question

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

Answer 1

When we add excess of base in the given solution of sodium hydroxide concentration of ions get decreases

Answer 2

Answer:

[OH] ions increases.

Explanation:

When the excess base is dissolved in the sodium hydroxide solution then the hydroxile ion concentration increases.

Since, the hydroxile ion is already present in NaOH and when again base which comprises of [OH] ions are added to it then its obvious that the concentration of hydroxile ion will increase.
