Calculation model: unless stated otherwise, 25°C and ideal-dilute aqueous concentrations. Use the constants supplied in each question. Square-root estimates require less than 5% ionization and negligible water contribution; buffer shortcuts require both components to remain appreciable. Simple Ksp solubilities here neglect hydrolysis, complexation and competing solids unless stated otherwise. HAc/Ac⁻ = CH₃COOH/CH₃COO⁻. These are teaching models, not experimental measurements.
