  1. Gram Equivalent Weight is used to measure the amount of a substance that can react with or replace a certain number of hydrogen ions or electrons. It is calculated by dividing the molar mass of the substance by its valence. On the other hand, Gram Molecular Weight is used to measure the mass of one mole of a substance.

  2. Equivalent weight focuses on the reactive capacity of a substance, while gram equivalent emphasizes the weight of a substance that is chemically equivalent to one mole of hydrogen ions or hydroxide ions.

  3. In chemistry, equivalent weight (also known as gram equivalent[1] or equivalent mass) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.

  4. 24 wrz 2024 · The mass of an acid or a base that will release or neutralize one gram molecule (mole) of hydrogen ion. A 1-mole solution of H 2 SO 4 contains 2 gram equivalents. A thousandth of a gram equivalent weight is a millequivalent.

  5. 18 cze 2024 · Difference Between Gram Equivalent and Equivalent Weight Definition. Equivalent weight is a more general term referring to the mass of a substance (element, ion, or compound) that can combine with or displace a fixed amount of another substance in a reaction.

  6. Gram Equivalent is specific to a particular reaction and describes the amount of a substance needed to react with or replace a certain quantity of reactive units, such as hydrogen ions or electrons. Equivalent Weight, on the other hand, provides a more general measure of a substance’s reactivity.

  7. The equivalent weight of an element is its gram atomic weight divided by its valence (combining power). Some equivalent weights are: silver (Ag), 107.868 grams (g); magnesium (Mg), 24.312/2 g; aluminum (Al), 26.9815/3 g; and sulfur (S, in forming a sulfide), 32.064/2 g.
