You need to be able to describe the reactions of acids with bases and metals. You should be able to work out the particular salt formed in the reaction.
Acids and bases
When acids react with bases, a salt and water are made:
- acid + metal oxide → salt + water
- acid + metal hydroxide → salt + water
Remember that most bases do not dissolve in water. But if a base can dissolve in water, it is also called an alkali.
Reactive metals
Acids will react with reactive metals, such as magnesium and zinc, to make a salt and hydrogen:
- acid + metal → salt + hydrogen
The hydrogen causes bubbling during the reaction, and can be detected using a lighted splint.
