Neutralization Reaction

▪ when an acid and a base react and neutralize each other to produce water (not all the time) and salt (always)
salt is a chemical compound composed of cations (positively charged ion) and anions (negatively charged ions)

acid + base → water + salt

Recall that in a precipitation reaction, a solid is formed as a product (precipitate).

Mg(OH)2(aq) + HCl(aq) → MgCl2(aq) + H2O(l)

• Mg(OH)2(aq) → base

• HCl(aq) → acid

• MgCl2(aq) → salt

• H2O(l) → water

Neutralization Reaction

CH3COOH(aq) + KOH(aq) → CH3COOK(aq) + H2O(l)

• CH3COOH(aq) → acid

• KOH(aq) → base

• CH3COOK(aq) → salt

• H2O(l) → water

Neutralization Reaction

Pb(NO3)2(aq) + KI(aq) → PbI2(s)↓ + KNO3(aq)
