а) Write a mathematical equation which shows how pH may be calculated. b) Distinguish between a strong acid and a weak acid. c) Write a chemical equation which shows how ethanoic acid (CH3COOH) diant, iŋHj-in aqueous solution. d) Write an expression which shows how the acid dissociation constant, Ka, of ethanoic acid (CH3COOH) may be calculated. e) If the pH of a 0.1 mol dm3 solution of ethanoic acid is 2.88 at 20 °C, calculate: (i) the hydroxonium ion concentration ([H3O*(aq)]) of this solution at 20 °C. (ii) the acid dissociation constant, Ka, for ethanoic acid at 20 °C.
