The chemical reaction is: One mole of aspirin plus one mole of water yields one mole of salicylic acid plus one mole of acetic acid. Aspirin=C9H8O4 Salicylic acid=C7H6O3 Acetic acid=C4H6O3
Because strontium sulfate is much less soluble in water than strontium chloride, sodium chloride, or sodium sulfate, this reaction is:Na2SO4 (aq) + SrCl2 (aq) => 2 NaCl (aq) + SrSO4 (s).
