- A salt is an ionic compound containing positive ions other than hydrogen ions and negative ions other than hydroxide ions. Most salts are strong electrolytes and are considered to be completely dissociated in aqueous solution.
Methods of Forming
- Neutralization reaction – 2HCl + Ca(OH)2 –» CaCl2 + 2H2O
- Simple displacement reaction – Zn + 2HCl –» ZnCl2 + H2
- Direct combination of elements – 2Fe + 3Cl2 –» 2FeCl3
- Double decomposition – ZnO + 2HNO3 –» Zn(NO3)2 + H2O
- Reaction of a metallic oxide with a nonmetallic oxide – MgO + SiO2 –» MgSiO3
