Answer:
Antacids include substances like sodium hydrogen carbonate or a combination of aluminium and magnesium hydroxide.
Heartburn is caused by stomach acidity, and antacids are used to alleviate the discomfort. They're administered orally to counteract acidity's effects. Antacids are alkaline ions that directly neutralise the stomach's gastric acids.
Explanation:
Lime is an alkaline mineral made mostly of calcium hydroxide. It's used to treat acidic soils since it neutralises the acidity. The alkaline characteristic of lime can neutralise sulphate, chloride, or phosphate groups in these acidic soils.
