Question

Write equations for the ionisation in water of :
A) hydrobromic acid
B) nitrous acid
C) carbonic acid
D) sulfuric acid
Ionization of an acid in water is typically the formation of hydronium ions, H<sub>3</sub>O<sup>+</sup> and the associated spectator ion. Example:
HCl + H<sub>2</sub>O -> HH<sub>3</sub>O<sup>+</sup> + Cl<sup>-</sup>

(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: H<sub>2</sub>CO<sub>3</sub>
(D) suphuric acid: H<sub>2</sub>SO<sub>4</sub>
oops! The example reaction should read:

HCl + H<sub>2</sub>O -> H<sub>3</sub>O<sup>+</sup> + Cl<sup>-</sup>
