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.
Inside this combination of a quiz and worksheet, you can find out how well you understand the calculation of equivalent weight. Questions focus on the n number of equivalents for an acid, and...
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.
The formula to calculate equivalent weight is: Equivalent weight = Atomic weight / Valence For example, the equivalent weight of sulfuric acid (H2SO4) is calculated as follows: Equivalent weight = Molecular weight / Acidic hydrogen ions Equivalent weight of H2SO4 = 98 / 2 = 49 So, the equivalent weight of sulfuric acid is 49 g/equivalent.
3 paź 2024 · The equivalent weight (EW) of a substance can be calculated using the formula: \[ \text{EW} = \frac{\text{MW}}{\Delta E} \] where EW is the equivalent weight, MW is the molecular weight, and ΔE is the number of electrons gained or lost by one molecule.
1 lut 2024 · The equivalent weight calculator provided here simplifies the process of determining equivalent weight, a fundamental parameter in chemistry. By inputting the molar mass and valence of a substance, users can quickly obtain the equivalent weight, aiding in various chemical calculations.
21 lis 2023 · The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents. Where "n" number of equivalents is the quantity of charge depending on the substance. If the substance is an...
