Question

Derive the formula for the ionization constant $(K_{b})$ for weak bases.

Open in App

Solution

A work base is a base that ionises only sightly in an area solution a base accepts a hydrogen ion from another substance for example a weak base Ammonia dissolve in water to give ammoniam ion by accepting $H^{+}$ ion
base ionistion constant $= k_{s} = \frac{[N H u^{+}] [O H^{-}]}{[N H_{3}]}$
