- 1Name the three main types of acid and their salts.1) hydrochloric acid: chloride
2) sulphuric acid: sulphate
3) nitric acid: nitrate - 2True or False? Alkalis are the same thing as bases.False.
Alkalis are similar to bases- they are soluble whilst bases are not. - 3Give an example of a base.- anything ending with oxide
- 4Give an example of an alkali.- anything ending with hydroxide
- 5Finish these off: a) acid + base/alkali b) acid + metal c) acid + metal carbonatea) acid + base/alkali = salt + water
b) acid + metal = salt + hydrogen
c) acid + metal carbonate = salt + water + carbon dioxide - 61) 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 carbonate1) 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 - 7What do all acids contain?Hydrogen
- 8REMEMBER:Soluble salts dissolve in water.
Insoluble salts do not dissolve in water. - 9What is a precipitate?A precipitate forms when you mix two chemicals. If one of the products is insoluble, we see it as a solid powder. This new solid is called a precipitate.
