What is the hydroxide ion concentration in a solution of NH3 with a pOH of 4.65?
Answer : The hydroxide ion concentration in a solution of ammonia is, \(2.2\times 10^{-5}M\)
Explanation : Given,
pOH = 4.65
pOH : It is defined as the negative logarithm of hydroxide ion concentration.
Mathematically it is represented as :
\(pOH=-\log [OH^-]\)
\(4.65=-\log [OH^-]\)
\([OH^-]=2.2\times 10^{-5}M\)
Therefore, the hydroxide ion concentration in a solution of ammonia is, \(2.2\times 10^{-5}M\)
