- Only metals above hydrogen in the reactivity series will react with dilute acids.
- The more reactive the metal then the more vigorous the reaction will be.
- Metals that are placed high on the reactivity series such as potassium and sodium are very dangerous and react explosively with acids.
- When acids react with metals they form a salt and hydrogen gas:
- The general equation is:
metal + acid ⟶ salt + hydrogen
- Some examples of metal-acid reactions and their equations are given below:
Acid-Metal Reactions Table
- In general we can summarise these reactions as follows:

Sulfuric acid reacts with metals and produces sulfate salts while hydrochloric acid produces chloride salts.
