Question

What is the hydroxide ion concentration in a solution of NH3 with a pOH of 4.65?

Answer 1

-5
[OH-]=2.24 X 10 M

Answer 2

Answer : The hydroxide ion concentration in a solution of ammonia is,
`2.2* 10^(-5)M`

Explanation : Given,

pOH = 4.65

pOH : It is defined as the negative logarithm of hydroxide ion concentration.

Mathematically it is represented as :

`pOH=-\log [OH^-]`

`4.65=-\log [OH^-]`

`[OH^-]=2.2* 10^(-5)M`

Therefore, the hydroxide ion concentration in a solution of ammonia is,
`2.2* 10^(-5)M`
