Here's how to solve these problems: 18.20 How many moles of H_3O^+ or OH^- must you add to 5.6 L of HA solution to adjust its pH from 4.52 to 5.25? Assume a negligible volume change. Step 1: Determine the initial and final hydronium ion concentrations. The initial pH is 4.52, so the initial hydronium ion concentration is: [H_3O^+]_1 = 10^-pH_1 = 10^-4.52 M = 3.01995 × 10^-5 M The final pH is 5.25, so the final hydronium ion concentration is: [H_3O^+]_2 = 10^-pH_2 = 10^-5.25
