Answer:
The hydroxide concentration in the solution is 0.0063 M.
Explanation:
The pH of the solution is defined as negative logarithm of [tex]H^+[/tex] concentration.
[tex]pH=-\log[H^+][/tex]
The pH of the ammonia solution is 11.8
pH + pOH = 14
pOH = 14 - 11.8 = 2.2
The pOH of the solution is defined as negative logarithm of hydroxide ion concentration.
[tex]pOH=-\log[OH^-][/tex]
[tex]2.2=-\log[OH^-][/tex]
[tex][OH^-]=0.0063 M[/tex]
The hydroxide concentration in the solution is 0.0063 M.
