Question	Answer
Name the three main types of acid and their salts.	1) hydrochloric acid: chloride 2) sulphuric acid: sulphate 3) nitric acid: nitrate
True or False? Alkalis are the same thing as bases.	False. Alkalis are similar to bases- they are soluble whilst bases are not.
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.
What 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.
