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.
Let us now try to define equivalent mass: All elements combine with each other according to the laws of chemical combination , and the number of parts by which an element combines with \(1\) part by mass of hydrogen, or \(8\) parts by mass of oxygen, or \(35.5\) parts by mass of chlorine, or one gram equivalent of any other element, is the ...
29 lip 2021 · Gram equivalent mass is defined as the mass of an element (compound or ion) that combines or displaces 1.008 g hydrogen or 8 g oxygen or 35.5 g chlorine. Consider the following reaction: Zn + H 2 SO 4 → ZnSO 4 + H 2
Equivalent weight is the mass of a substance that reacts with or replaces one mole of hydrogen ions or electrons. It is expressed in grams per equivalent. On the other hand, gram equivalent is the mass of a substance that reacts with or replaces one gram equivalent of hydrogen ions or electrons.
24 sty 2016 · Equivalent weight is the (mass of) number of moles of one reactant in a balanced reaction (or product) divided by the number of moles of another. In the simple case where we have two reactants which combine 1:1, then the mass of 1 mole of either is its equivalent weight.
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.
Gram equivalent weight is determined by dividing the molar mass of a substance by its valence, which reflects the number of hydrogen ions or electrons involved in a reaction. On the other hand, gram molecular weight is calculated by summing up the atomic masses of all the atoms in a molecule.
