What Is "Gram-Equivalent"?

Hello, my name is Walter Unglaub and this is what is gram-equivalent? Gram-equivalent is a notion that is used in the fields of chemistry and chemical engineering. And what it corresponds to is the mass of a substance that either reacts with or supplies exactly one mole of protons. Which I'll denote as p+ in acid base reactions. Or alternatively it would be the mass of a substance that reacts with or supplies exactly one mole of electrons in redux reactions. Where redux in shorthand for reduction oxidation reaction. And one mole is defined via of Avogadros number. So one mole is actually equal to 6.022 times 10 to the 23 particles. So when you have this many particles in a given substance of protons or electrons, depending on the reaction. Then you have your gram-equivalent.
