Write equations for the ionisation in water of :

B) nitrous acid
C) carbonic acid
D) sulfuric acid

Ionization of an acid in water is typically the formation of hydronium ions, H3O+ and the associated spectator ion. Example:
HCl + H2O -> HH3O+ + Cl-

(A) Hydrobromic acid: HBr
It is very similar to ionization of hydrochloric acid above.
For the rest, the reactions are similar, but do balance the equations.
(B) nitrous acid: HNO2
(C) carbonic acid: H2CO3
(D) suphuric acid: H2SO4
oops! The example reaction should read:

HCl + H2O -> H3O+ + Cl-
