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-
