Part A:Part B: Predict whether aqueous solutions of the following compounds will be acidic, basic or neutral. If the solution would be acidic or basic, circle the ion that causes the pH to change. a) NH Brb ) FeCl, c) K,CO, d) KCIO e) NaBr f) MgCl, g) NaF h) LiNO Two unknown acid solutions are both labelled 0.50 M. How could you determine which is the strong acid and which is the weak acid? Explain.
Identify solutions of the following salts as acidic, basic or neutral. Identify solutions of the following salts as acidic, basic or neutral. NaCl NaCN NH4Br KNO2 KOH NH3 HF KI
xc. Predict semi-quantitatively whether the following solutions are acidic, basic, or nearly neutral. (a) NH4NO2 (b) NH4F (c) NH4CN (d) NaHCO (e) K2HPO4 (f) (NHA)2SO The first part is solved below. Use similar reasoning to make predictions for the other solutions (a) Ka for NH,-5.6x 1010 and Ko for NO is 2.2x 10. Since the Ka is about 25 times larger than Kb, the solution should be acidic.
