There are 3 moles of
N H 4 +
per 1 mole of salt and 1 mole of
P O 4 3 −
per mole of salt, the total ionic concentrations must be
2.7 M of N H 4 + , and 0.9 M of P O 4 3 −
In a 0.9 M solution of ammonium phosphate, the concentration of ammonium ions N H 4 + is 2.7 M, while the concentration of phosphate ions P O 4 3 − is 0.9 M. This is due to the dissociation of ammonium phosphate into these ions. Therefore, the total concentration of ions in solution can be described based on their stoichiometry from the dissociation reaction.
