Asked by Jay
Hi there,
ok, my question stated "Use information from acid/base table and the value of Kw t ocalulate the base ionization constant, Kb, of the following bases:
a)hypochlorite ion
b) nitrite ion
c) benzoate ion
I looked at my acid/base table but it only gives values for hypochlorus acid, nitric acid, benzoic acid,.....
What to do?

Two comments.
#1. You don't means nitric acid. You mean nitrous acid, HNO2.
#2. You found the Ka for HOCl, HNO2, and C6H5COOH. You want <b>Kb (not Ka)</b> for the anion; i.e., OCl^-, NO2^-, and C6H5COO^-. Easy to do.
KaKb = Kw. You know Kw, you find Ka in the tables for the corresponding acids, solve for Kb for the conjugate base.
