Acid Reactions & Salts
Describe and write word equations for the reactions of acids with metals, alkalis (neutralisation), and metal oxides/hydroxides, identifying the salt produced in each case
Suggested ages 12–13
Evidence of understanding
- Writes word equations for: acid + metal → salt + hydrogen; acid + alkali → salt + water; acid + metal oxide → salt + water
- Names the salt formed from a given acid and base (e.g. hydrochloric acid + sodium hydroxide → sodium chloride)
- Describes the test for hydrogen gas (squeaky pop)
- Explains what neutralisation means and gives a practical example (indigestion tablets, treating acidic soil)
Assessment prompt
If Acid Reactions & Salts was asked how an indigestion tablet works to relieve stomach acid, could they explain what type of chemical reaction is happening and write a simple word equation for it?
