I'll solve these neutralization reactions step by step. Let me work through each one carefully.
Understanding Neutralization Reactions:
- Acid + Base → Salt + Water
- The H⁺ from the acid combines with OH⁻ from the base to form H₂O
- The remaining ions form the salt
Let me solve each reaction:
1. HCl + NaOH →
- HCl (acid) + NaOH (base)
- Products: NaCl + H₂O
- Balanced: HCl + NaOH → NaCl + H₂O ✓
2. HNO₃ + KOH →
- HNO₃ (acid) + KOH (base)
- Products: KNO₃ + H₂O
- Balanced: HNO₃ + KOH → KNO₃ + H₂O ✓

- Products: KBr + H₂O
- Balanced: HBr + KOH → KBr + H₂O ✓
4. HCl + LiOH →
- HCl (acid) + LiOH (base)
- Products: LiCl + H₂O
- Balanced: HCl + LiOH → LiCl + H₂O ✓
5. HF + Ba(OH)₂ →
- HF (acid, monoprotic) + Ba(OH)₂ (base, has 2 OH)
- Need 2 HF to react with 1 Ba(OH)₂
- Products: BaF₂ + H₂O
- Balanced: 2HF + Ba(OH)₂ → BaF₂ + 2H₂O ✓
6. H₂SO₄ + Ca(OH)₂ →

- Balanced: H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O ✓
7. H₂CO₃ + NaOH →
- H₂CO₃ (diprotic acid, has 2 H⁺) + NaOH (monoprotic base)
- Need 2 NaOH to react with 1 H₂CO₃

- Balanced: H₂CO₃ + 2NaOH → Na₂CO + 2H₂O ✓
8. H₃PO₄ + Ca(OH)₂ →
- H₃PO₄ (triprotic acid, has 3 H⁺) + Ca(OH)₂ (has 2 OH⁻)
- Need to balance: 2 H₃PO₄ (6 H⁺) + 3 Ca(OH)₂ (6 OH⁻)
- Products: Ca₃(PO₄)₂ + H₂O
- Balanced: 2H₃PO₄ + 3Ca(OH)₂ → Ca₃(PO)₂ + 6H₂O ✓
9. HC₂H₃O₂ + KOH →
- HC₂H₃O₂ (acetic acid, monoprotic) + KOH (base)
- Products: KC₂H₃O₂ + H₂O
- Balanced: HC₂H₃O₂ + KOH → KC₂H₃O₂ + H₂O ✓
10. H₂CO₃ + Sr(OH)₂ →
- H₂CO₃ (diprotic acid, has 2 H⁺) + Sr(OH)₂ (has 2 OH⁻)
- Products: SrCO₃ + H₂O
- Balanced: H₂CO₃ + Sr(OH)₂ → SrCO₃ + 2H₂O ✓
11. HNO₃ + Zn(OH)₂ →
- HNO₃ (monoprotic acid) + Zn(OH)₂ (has 2 OH)
- Need 2 HNO₃ to react with 1 Zn(OH)₂
- Products: Zn(NO₃)₂ + H₂O
- Balanced: 2HNO₃ + Zn(OH)₂ → Zn(NO₃)₂ + 2H₂O ✓
12. HCl + Al(OH)₃ →
- HCl (monoprotic acid) + Al(OH)₃ (has 3 OH⁻)
- Need 3 HCl to react with 1 Al(OH)₃
- Products: AlCl + H₂O
- Balanced: 3HCl + Al(OH)₃ → AlCl₃ + 3H₂O ✓
