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.
8 mar 2020 · Learn the definition and formula of equivalent weight, the weight of a substance that contains a single reactive proton or hydroxide ion. See examples of acids and bases with different equivalent weights and how to use a calculator.
29 lip 2021 · Learn how to calculate gram equivalent mass of elements, compounds and ions based on equivalent mass and hydrogen, oxygen and chlorine references. Find examples and diagrams for redox reactions using gram equivalent concept.
19 kwi 2024 · Gram equivalent weight is the equivalent weight given in mass units. The calculated equivalent weight and the gram equivalent weight are equal numerically. E q = MW / n
Equivalent weight is used in the calculation of normality. The normality of a solution is defined as the number of gram equivalents of the solute present per litre of the solution. It is represented by the symbol, N. Normality = gram equivalent of the solute/volume of the solution in litres.
24 sty 2016 · The formula you were talking about gives the equivalent weight of an element (can be extended to be used with ions). Equivalent weight = (Atomic mass)/(Valency) This could be intuitive and obvious for some.
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.
