Respuesta :
Answer : The hydroxide ion concentration in a solution of ammonia is, [tex]2.2\times 10^{-5}M[/tex]
Explanation : Given,
pOH = 4.65
pOH : It is defined as the negative logarithm of hydroxide ion concentration.
Mathematically it is represented as :
[tex]pOH=-\log [OH^-][/tex]
[tex]4.65=-\log [OH^-][/tex]
[tex][OH^-]=2.2\times 10^{-5}M[/tex]
Therefore, the hydroxide ion concentration in a solution of ammonia is, [tex]2.2\times 10^{-5}M[/tex]
