Na2co3 dissociation.

No, H2CO3 is not a strong acid as it does not dissociate completely in an aqueous solution. The carbonic acid molecule has two hydrogen atoms to lose i.e. it is a diprotic acid and, therefore, has two acid dissociation constants, Ka. The value of the acid dissociation constant is the reflection of the strength of an acid.The ammonium ion is the conjugate acid of the base ammonia, NH 3; its acid ionization (or acid hydrolysis) reaction is represented by.
