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.
Learn the definition, history and calculation of equivalent weight in chemistry. Equivalent weight is the mass of a substance that reacts with or displaces a fixed quantity of another substance.
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
24 sty 2016 · By definition, equivalent weight is the mass of the substance that would react with 1g of hydrogen. Therefore you must divide the mass by 2 to get equivalent weight. In fact, this formula based definition of equivalent weight of an element is identical with the definition mentioned earlier in this answer.
21 lis 2023 · Learn how to calculate the equivalent weight of elements, ions, acids and bases using the formula EW = MW/n. See examples of equivalent weight problems and how to use it in chemistry.
Learn how to calculate the equivalent weight of a compound based on its molecular weight and the number of equivalents of protons or hydroxides it contains. See examples of acid-base reactions and how to measure the experimental equivalent weight by volumetric analysis.
The formula to calculate the equivalent mass of an element is given by \[\text{Equivalent Mass}=\dfrac{\text{Atomic Mass}}{\text{Valency}}.\] Sometimes if we don't know the valency of the atom, we cannot find the equivalent mass.
