Give an example of a base. | - anything ending with oxide |
Give an example of an alkali. | - anything ending with hydroxide |
Finish these off: a) acid + base/alkali b) acid + metal c) acid + metal carbonate | a) acid + base/alkali = salt + water b) acid + metal = salt + hydrogen c) acid + metal carbonate = salt + water + carbon dioxide |
1) sulphuric acid + copper carbonate 2) nitric acid + sodium oxide 3) hydrochloric acid + lead 4) sulphuric acid + zinc hydroxide 5) nitric acid + copper 6) hydrochloric acid + magnesium carbonate | 1) copper sulphate + water + carbon dioxide 2) sodium nitrate + water 3) lead chloride + hydrogen 4) zinc sulphate + water 5) copper nitrate + hydrogen 6) magnesium chloride + water + carbon dioxide |
What do all acids contain? | Hydrogen |
REMEMBER: | Soluble salts dissolve in water. Insoluble salts do not dissolve in water. |
