1. 10.5 Equilibria in Salt Solutions LO: I understand how the pH of a salt solution comes about.

2. Sodium ethanoate is the salt of a acid and a base. The pH of sodium ethanoate is. CH 3 COO - Na + (s)CH 3 COO - (aq)Na + (aq)++water Sodium ethanoate completely splits into when dissolved in water: OH - (aq) CH 3 COOH(aq) H + (aq) + +H 2 O(l) LO: I understand how the pH of a salt solution comes about. weak strong ions >7

3. Ammonium chloride is the salt of a acid and a base. The pH of ammonium chloride is. NH 4 + Cl - (s)NH 4 + (aq)Cl - (aq)++water Ammonium chloride also completely splits into. when dissolved in water: H + (aq) NH 3 (aq) + H 2 O(l) OH - (aq) + +H 2 O(l) LO: I understand how the pH of a salt solution comes about. strong weak ions <7

4. Sodium chloride is the salt of a acid and a base. The pH of sodium chloride is. Na + Cl - (s)Na + (aq)Cl - (aq)++water LO: I understand how the pH of a salt solution comes about. strong 7 Neither ion is involved in an equilibrium.
