1. The mass of the element which combines with 8 grams of oxygen is the equivalent mass of the element. ... equivalent of a more electropositive metal displaces one gm equivalent of a less electropositive metal from its salt solution.
2. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water.
3. It is based on the fact that one gm. equivalent of a more electropositive metal displaces one gm equivalent of a less electropositive metal from its salt solution.
