The concentration of OH⁻ in 10⁻³ M HCl isBuffer solutions resist changes in pH because they containpH of a buffer made from 0.10 M CH₃COOH and 0.10 M CH₃COONa is closest to (pK_a = 4.74)Hydrolysis of CH₃COONa in water produces a solution that isSolubility product (K_sp) of a sparingly soluble salt AgCl is given byCommon-ion effect occurs whenIf K_sp of AgCl is 1.6×10⁻¹⁰ at 25 °C, solubility of AgCl in pure water is approximately
