What is Normality?
The concentration of the given solution during the specific chemical process is determined by normality. In other words, normality can be defined as the number of grams of solute equivalents present in each liter of solution.
Normality is generally used in acid-base chemistry, to determine the concentrations. In precipitation, reactions calculate the number of ions that are expected to precipitate in a given reaction. And in redox reactions, determine how many electrons a reducing or oxidizing chemical can donate or take.
- Normality is represented by the letter “N.”
- The gram/liter is the SI unit. Other units used for normality are eq L-1 or meq L-1.
- Normality is also called by the name equivalent concentration.
Normality – Definition, Formula, Equations and Solved Examples
The normality formula is used to measure the concentration of a solution like molarity and molality. Normality is a measure of the number of grams equivalent to solute present given volume of the solution. Redox reactions, precipitation reactions, and acid-base chemical reactions all often make use of normality. It depends on the temperature and the chemical reaction being observed.
The term “equivalent concentration” describes how reactive a solution is. This is frequently used in redox reactions and acid-base reactions. In physical chemistry, one of the important terms used is the normality formula.
