Calculate the pH of a 0.10 M solution of aluminum chloride, which dissolves completely in water to give the hydrated aluminum ion [Al(H2O)6]3+ in solution. Al3+(aq) + H2O(l) → [Al(H2O)6]3+(aq) [Al(H2O)6]3+(aq) + H2O(l) → [Al(H2O)5OH]2+(aq) + H3O+(aq) Ka = 1.4 x 10-5 Soda water (carbonated water) is a solution of carbon dioxide in water. The solution is acidic because CO2 reacts with water to form carbonic acid, H2CO3. What are [H3O+], [HCO3-], [CO3-2] in a saturated solution of CO2 with...
