1 gram equivalent refers to the amount of a substance that reacts with or supplies one mole of hydrogen ions (H+) or electrons in a chemical reaction. It’s a useful measure in stoichiometry for understanding reactant amounts. For acids, it is the amount that can furnish one mole of H+ ions; for bases, it is the amount that can furnish one mole of OH- ions.

FAQs & Answers

  1. What is the significance of a gram equivalent in chemistry? A gram equivalent helps quantify the reactive capacity of a substance in relation to other reactants in a chemical reaction.
  2. How do you calculate gram equivalents? To calculate gram equivalents, divide the substance's molar mass by its valence or reactiveness in the equation.
  3. What is the difference between gram equivalent and molar mass? Molar mass is the weight of one mole of a substance, while gram equivalent refers to the amount that reacts with a specific quantity of hydrogen ions or electrons.
