6 Δεκ 2018 · In a more formal definition, the equivalent is the amount of a substance needed to do one of the following: react with or supply one mole of hydrogen ions (HX+ H X +) in an acid-base reaction. react with or supply one mole of electrons in a redox reaction.
In chemistry, the equivalent concentration or normality (N) of a solution is defined as the molar concentration c i divided by an equivalence factor or n-factor f eq: N = c i f e q {\displaystyle N={\frac {c_{i}}{f_{\rm {eq}}}}}
27 Ιουλ 2024 · The normality of a solution is the gram equivalent weight of a solute per liter of solution. It may also be called the equivalent concentration. It is indicated using the symbol N, eq/L, or meq/L (= 0.001 N) for units of concentration. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl.
How to Calculate Normality? The following are the steps to calculate the normality: Find the information about the equivalent weight of the reacting substance or the solute. Find out the number of gram equivalent of solute by calculation. Calculate the volume in litres. Then calculate normality using the formula.
10 Ιουν 2019 · The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute.
12 Σεπ 2021 · Although a solution of H 2 SO 4 has a single molarity, its normality depends on its reaction. We define the number of equivalents, n, using a reaction unit, which is the part of a chemical species that participates in the chemical reaction.
As per the standard definition, normality is described as the number of gram or mole equivalents of solute present in one litre of a solution. When we say equivalent, it is the number of moles of reactive units in a compound.
