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, 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-

A) Hydrobromic acid (HBr) ionizes in water to produce hydrogen ions (H+) and bromide ions (Br-). The equation is as follows:

HBr + H2O → H3O+ + Br-

B) Nitrous acid (HNO2) ionizes in water to produce hydrogen ions (H+) and nitrite ions (NO2-). The equation is as follows:

HNO2 + H2O → H3O+ + NO2-

C) Carbonic acid (H2CO3) ionizes in water to produce hydrogen ions (H+) and bicarbonate ions (HCO3-). The equation is as follows:

H2CO3 + H2O → H3O+ + HCO3-

D) Sulfuric acid (H2SO4) ionizes in water to produce hydrogen ions (H+) and sulfate ions (SO4^2-). The equation is as follows:

H2SO4 + H2O → H3O+ + SO4^2-
