Question

Equivalent Weight of CaCl₂

Answer 1

Equivalent weight: It is the mass of one equivalent, that is the mass of a given substance that will combine with or displace a fixed quantity of another substance.

Formula to calculate the equivalent mass

• Equivalent weight = Molecular weight/Valency.
• Valency =2
• The molecular weight of CaCl₂ = 110g/mol
• Equivalent weight = 110/2

= 55

• Hence the equivalent weight of CaCl₂ is 55.
