What is the Difference Between Gram Equivalent and Equivalent Weight?

The key difference between gram equivalent and equivalent weight lies in the unit of measurement:

• Gram Equivalent: This term refers to the mass (in grams) of an element, group, or compound that participates in a chemical reaction, usually just one type of reaction. It is a specific case of equivalent weight, where the unit of measurement is grams.
• Equivalent Weight: This term refers to the mass of an element, group, or compound that participates in a chemical reaction. The unit of measurement can be any unit, not just grams. Equivalent weight is typically determined by dividing the molar mass of the desired substance by the number of moles of the reacting species.

In summary:

• Gram equivalent is the mass of an equivalent in the unit of grams, while equivalent weight is the mass of an equivalent in any unit of measurement.
• Both terms describe the amount of a substance involved in a chemical reaction, but gram equivalent is a specific case of equivalent weight with grams as the unit of measurement.

Comparative Table: Gram Equivalent vs Equivalent Weight

Here is a table comparing the difference between gram equivalent and equivalent weight:

The key difference between gram equivalent and equivalent weight is that gram equivalent describes the mass in grams of an element, group, or a compound, while equivalent weight is the mass of a substance in grams that is chemically equivalent to another substance, typically oxygen.
