ANSWER

What is normality of a solution

Posted by Krishna Agarwal 5 years, 9 months ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 5 years, 9 months ago

Normality can be defined as gram equivalent of solute dissolved in one cubic decimeter or one liter of solution. The unit of normality is N. It is most preferred during titration calculations. Normal solutions have normality equal to unity.

Normality = <nobr>Molecular mass/Equivalent mass of solute</nobr>

Decinormal is calculated as follows:

N/10 = 0.1 N

Seminormal is calculated as follows:

N/2 = 0.5 N

The strength of a solution can be calculated by finding the product of equivalent mass and normality. It is expressed in grams per liter.
