1. Key Ideas

Every time you take an antacid tablet for heartburn, you're triggering an acid-base reaction in your stomach — and the salt it produces determines whether the treatment works or makes things worse. The chemistry of neutralisation is in your medicine cabinet.

The products of acid-base neutralisation (salt + water)
How to identify the salt from an acid-base reaction before balancing

2. Success Criteria

By the end, you should be able to:

The products of acid-base neutralisation (salt + water)
The products of acid-carbonate reactions (salt + water + CO₂)
Which acid produces which anion in the salt

3. Key Terms

acidA substance that donates protons (H⁺) or accepts electron pairs, according to context.

baseA substance that accepts protons (H⁺) or donates electron pairs, according to context.

soluble baseA substance that accepts protons (H⁺) or donates electron pairs, according to context.

alkaliAlkali vs base: NaOH and KOH are alkalis (soluble bases).

Common basesA substance that accepts protons (H⁺) or donates electron pairs, according to context.

Synthesis reactionA reaction where two or more reactants combine to form a single product.
