Normality in chemistry is one of the expressions wont to measure the concentration of an answer. It’s abbreviated as ‘N’ and is usually named because of the equivalent concentration of an answer. It’s mainly used as a measure of reactive species in a very solution and through titration reactions, particularly in situations involving acid-base chemistry.
Per the quality definition, normality is described because of the number of gram or mole equivalents of solute present in one litre of an answer. After we say equivalent, it’s the number of moles of reactive units during a compound.
How to Calculate Normality?
There are certain tips that students can follow to calculate normality.
The first tip that students can follow is to collect information about the atomic weight of the reacting substance or the solute. Find the textbook or reference books to learn relative molecular mass and valence.
The second step involves calculating the no. of gram equivalent of solute.
Students should remember that the degree is to be calculated in litres.
Finally, normality is calculated using the formula and replacing the values.
Calculation of Normality in Titration
Titration is the gradual addition of an answer of a known concentration and volume with another solution of unknown concentration until the reaction approaches its neutralization. To seek out the normality of the acid and base titration:
N1 V1 = N2 V2
