Equivalent weight is the mass of a substance that reacts with or displaces a fixed quantity of another substance. Learn about its history, calculation, and applications in chemistry.
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.
19 kwi 2024 · Equivalent weight is defined as the ratio of the molecular weight of the solute to the valency of the solute. The equivalent weight of the substance varies according to the reaction it undergoes. The normality of the solution is calculated using the equivalent weight of the substance.
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.
An equivalent weight which is also known as gram equivalent can be defined as is the mass of one equivalent, that is the mass of a given substance that will combine with or displace a fixed quantity of another substance.
