What is the equation for the acid ionization constant of HNO3?

1 Answer

Jul 3, 2018

$K_{a} = \frac{[H^{+}] [N O_{3}^{-}]}{H N O_{3}}$ $K_a = ([H^+][NO_3^-])/[HNO_3]$

Explanation:

The equation for ionization of nitric acid, $H N O_{3}$ $HNO_3$ can be written as

$H N O_{3} (a q) \to H^{+} (a q) + N O_{3}^{-}$ $HNO_3(aq) -> H^+(aq) + NO_3^-$ $(a q)$ $(aq)$

From the equation, the acid ionization constant, $K_{a}$ $K_a$ , can be written as

$K_{a} = \frac{[H^{+}] [N O_{3}^{-}]}{H N O_{3}}$ $K_a = ([H^+][NO_3^-])/[HNO_3]$
