Calculate the concentrations of solution 7 & 8 Sol Conc. NH3 (M) 7 8 M₂ = M₂V₁ V₂ Conc. NH4* (M) used to solve for the concentrations Conc.HCI (M) pH 8.89 3.7 Compare solutions 4, 7 & 8. The ingredients are essentially the same, but the solutions of 7 & 8 should have a dramatically different pH. Why did 7 work as a buffer, but 8 did not? Compare the concentration of NH3 vs the concentration of HCI.
