What is Equivalent Weight?

Equivalent weight is defined as the ratio of the molecular weight of the solute to the valency of the solute. The equivalent weight of the substance varies according to the reaction it undergoes. The normality of the solution is calculated using the equivalent weight of the substance. The general formula to calculate the equivalent weight is,

Equivalent Weight Formula

Equivalent Weight = Molecular Weight / (n-factor)Valency

Equivalent Weight

The most commonly used phrase in chemistry is “equivalent weight,” which is also one of the fundamental concepts in physical chemistry. Equivalent weight commonly referred to as a gram equivalent is the mass of one equivalent or the mass of a particular material that will combine with or replace a specific amount of another substance. To say it another way, the mass of a substance that can displace 1.008 grams of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine is its gram equivalent or equivalent weight. Let us study the Equivalent Weight in detail in this article.
