Dilute or Concentrated Acids (WJEC GCSE Chemistry)

Dilute or Concentrated Acids

• A dilute acid has the acid molecules mixed with a large amount of water

• Concentrated acids have little to no water molecules mixed with the acid molecules

Dilute and concentrated acids

A highly concentrated acid has a large number of acid molecules in the solution

• Different acids can be dilute or concentrated but specific acids are strong or weak

• For example

  • Hydrochloric acid (pH 1) is classed as a strong acid which could either be dilute or concentrated

  • Ethanoic acid (pH 3) is classed as a weak acid which again could either be dilute or concentrated
