Interpretation: The difference between normality and molarity needs to be explained.
Concept introduction: Since majority of the reaction in laboratories are carried out in solution it is important to understand how to express the amount of substance in the solution. The concentration of the solution can be expressed in both normality and molarity.
Answer to Problem 6RQ
Molarity is a measure of the number of moles per liter of solution, on the other hand the normality is variable unit of concentration which depends on the nature of reactive species in the solution.
Explanation of Solution
Molarity can be defined as the number of moles of solute in 1 litre of solution. Thus,
Normality mainly used in acid-base reaction where it gives more in-depth information of the concentration of the solution.
Molecules reactive capacity is known as
Simple relation between normality and molarity is as follows,
For example, let the concentration of
1 mol of
In similar way
Molarity is a measure of the number of moles per liter of solution, on the other hand the normality is variable unit of concentration which depends on the nature of reactive species in the solution.
