Acid Base Neutralization Reaction

1. Base + acid → salt + water
Example: HCl + KOH → KCl + H2O
2. Base oxide + acid → salt + water
Example: 2NaOH + CO2 → Na2CO3+ H2O
3. Base oxide + acid → salt + water
Example: CaO + 2HCl → CaCl2 + H2
4. Acid oxide + base oxide → salt base
Example: SO3 + CaO → CaSO4
5. Metal + acid → salt + H2 gas
Example: Fe + H2SO4 → FeSO4 + H2
6. Metal1 + salt1 → salt2 + metal2
Example: FeSO4 + Ca →
Fe + CaSO4

Terms: Salting at fifth number, the metal must be on the left H + in the array Volta. Salting at sixth number, metal1 must be located on the left in metal2 array Volta.
Volta array:
Li - K - Ba - Ca - Na - Mg - Al - Mn - Zn - Cr - Fe - Co - Ni - Sn - Pb - (H) - Sb - Bi - Cu - Hg - Ag - Au - Co
