Brønsted–Lowry theory of acids and bases past paper questions

Chemistry 9701 · Equilibria. 1 state the names and formulas of the common acids, limited to hydrochloric acid, HCl, sulfuric acid, H2SO4, nitric acid, HNO3, ethanoic acid, CH3COOH 2 state the names and formulas of the common alkalis, limited to sodium hydroxide, NaOH, potassium hydroxide, KOH, ammonia, NH3 3 describe the Brønsted–Lowry theory of acids and bases 4 describe strong acids and strong bases as fully dissociated in aqueous solution and weak acids and weak bases as partially dissociated in aqueous solution 5 appreciate that water has pH of 7, acid solutions pH of below 7 and alkaline solutions pH of above 7 6 explain qualitatively the differences in behaviour between strong and weak acids including the reaction with a reactive metal and difference in pH values by use of a pH meter, universal indicator or conductivity 7 understand that neutralisation reactions occur when H+(aq) and OH–(aq) form H2O(l) 8 understand that salts are formed in neutralisation reactions 9 sketch the pH titration curves of titrations using combinations of strong and weak acids with strong and weak alkalis 10 select suitable indicators for acid-alkali titrations, given appropriate data (pKa values will not be used)
