The $p K_{b}$ value of ammonium hydroxide is 4.75. An aqueous solution of ammonium hydroxide is titrated with HCl. The pH of the solution at the point where half of the ammonium hydroxide has been neutralized will be

Options:

Answer:

Solution:

$p O H = p K_{b} + l o g \frac{[S a l t]}{[B a s e]}$
when [Salt] = [Base]
So, pOH $= p K_{b} = 4.75$
So, pH = 14 – 4.75 = 9.25.
