Question

Part 2 (acid/base) 4. Consider the following questions about acids and bases. a) Which of these solutions will have the highest concentration of OH ions? Which will have the lowest? i) 0.60 M CH3NH2 ii) 0.25 M Sr(OH) iii) 0.35 M LiOH) b) Predict the product of the following reaction. Make sure the reaction is balanced. Na)+Ba(OH) (ag) c) Write a net ionic equation for b) d) Identify the acid and the base in the following reaction (remember the Bronsted Lowry definition). NaCH,COO+NHCI- NaCI+CH COOH NH

Answer 1

Sr(OH) _2 rightleftharpoons sr^2 + 2Oh^- Li(OH) rightleftharpoons Li + OH^- CH_3 ma_2 leftarrow ro OH^- highest sr(OH) _2 (0.25m) lowest 0.60M (UA_3 MA_2) 2HNO_3 (aq) + Ba(OH) _2 (aq) = Ba(NO_3) (aq) + 2H_2_o (l) 2HNO_3 (aq) + Ba(OH) _2 (aq) = Ba(NO_3) (aq) + 2H_2_o (l) 2H^+ (aq) + 2NO^-_3 (aq) + Ba^2a + (aq) + 2OH^-(aq) = Ba^2 + (aq) + 2NO^-_3 (aq) + 2H_2O(l) therefore 2H^+ (aq) + 2Oh^-(aq) = 2H_2O(l) H^+ (aq) + OH^-(aq) = H_2O(l)
