# What is the pH of 0.35 M KOBr solution?

Oct 17, 2016

You need to provide $p {K}_{a}$ for hypobromous acid.

#### Explanation:

We wish to assess the equilibium:

$K O B r \left(a q\right) + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s H O B r \left(a q\right) + H {O}^{-} \left(a q\right)$

K_b=([HO^-][HOBr])/([""^(-)OBr])

Without the ${K}_{b}$ value we are shot birds. You will find ${K}_{a}$ in the literature, and this we can use to assess ${K}_{b}$.
