The use of a single arrow in the following chemical equation illustrates that the strong acid completely ionized. HBr(aq) + H2O(l) —–> H3O+ (aq) + Br- (aq)

Water is a reactant in the ionization of a weak acid, so is included in the equation for the ionization constant for that weak acid.

Identify the Brønsted-Lowery Acid in the following reaction. H2SO4(aq) + NH3(aq) —– > 2 NH4+(aq) + SO42-(aq)

A Bronsted-Lowery acid donates a proton, H+, to another compound.

Determine the pH of a solution in which the hydronium ion concentration is 3.5 x 10-4 M.
