WebNOTE: Normality is a measure of concentration that is equal to the gram equivalent weight per liter of solution. Gram equivalent weight is a measure of the reactive capacity of a molecule. As an example a solution containing $\pu{1M}$ $\ce{H2SO4}$ is actually $\pu{2N}$ as each molecule dissociates to give 2 $\ce{H+}$ ions. I hope that clears it. WebApr 8, 2024 · We can define the equivalent weight of an element as the atomic weight divided by valence electrons in compounds. Its unit is atomic mass unit, the amount of substance in gram is equal to the equivalent weight known as the gram equivalent weight. For example, hydrogen has atomic weight of 1.008 and the valence electron in …
In chemistry, equivalent weight (also known as gram equivalent ) 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.

The different definitions came from the practice of quoting gravimetric results as See more WebSep 4, 2024 · Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute’s role in the reaction determines the solution’s normality. Normality is also known as the equivalent concentration of a solution.
WebIt is also known as gram equivalent. The equivalent of any substance is given by the charge it carries on itself. Thus, the equivalent weight is obtained by the ratio of the … WebThe gram-equivalent weight of a base is that weight of the base that contains 1 gram-equivalent weight (17.008 g) of replaceable OH -. Examples. The gram-equivalent weight of NaOH is 1 mole (i.e. 1 gram-formula weight) , that of Mg(OH) 2 is ½ mole, and of Al(OH) 3 is ⅓ mole. 4. Simple normal salt.
