Ka is the acid dissociation constant while pH is the measure of the acidity or basicity of aqueous or other liquid solutions. Generally, the problem usually gives an initial acid concentration and a \(K_a\) value. WebNitrous acid (also known as nitric(III) acid) has the formula HNO 2. It is sometimes written as HONO to show the way it is joined up. Nitrous acid decomposes very readily and is always made in situ.
