explain ou are given us solutions of the following at 25°C. Predict whether each solution will be acidic, basic, (a) posm at, KC,H,O, The cation, K", belongs to group 1 of the periodic table and will not affect the pH. The anion, C,H,O, solution of potassium acetate --Sec . weak acid and will act as a base, making a (b) barum chlorate, Balco), The cation Therefore, belongs to grove 2 of the periodic table and will not affect the p. Thenion Co ution of bar b e s the conte base of a strong and notect the (c) ammonium hypochlorite, NH CHO The cation, NH', is the conjugate acid of a weak base and will tend to lower the pH. The anion, CIO, is the conjugate base of a weak acid and will end to raise the ph. The of CIO (2.5x10) is greater than the of NH (5.6x10-) Therefore, when ammonium hypochlorite is dissolved in more hydroxide ions will be produced than hydronium ions. Consequently, a solution of ammonium hypochote (d) aluminum iodide, All, The anion, 1 is the conjugate base of a strong acid and will not affect the pol. The cation, A . is a small metal ion with a large positive charge It acts as a Lewis acid, attracting the unshared electron pairs of watermolecules. In this interaction, the A ton puis lectron density towards and weakes the 0-H bonds of the water molecules leading to the transfer of hydrogen fons to reighboring water molecules to produce H.O' Because the concentration of Hoon increases
