EVALUATION

The chapter-end evaluation. Part I ('Choose the correct answer') is 23 multiple-choice questions spanning Bronsted-Lowry and Lewis acid-base theory, conjugate pairs, pH/pOH calculations for strong-acid/strong-base mixtures, buffer identification and the Henderson-Hasselbalch ratio, salt hydrolysis (including the ammonium-acetate degree-of-hydrolysis relation), and solubility-product problems (including NEET-sourced items on $Ag_2C_2O_4$, $BaSO_4$ and $Ca(OH)_2$). Part II ('Answer the following questions') is 27 short/long-answer questions covering definitions (pH, solubility product, ionic product of water), derivations (Ostwald's dilution law, the hydrolysis constant/degree of hydrolysis of a strong-acid/weak-base salt), and a long run of numerical p …
