What is the normality of a sulfuric acid solution that is 18 M?

Solution:

The molarity of a solution is defined as moles of solute per liter of solution. The given concentration of sulfuric acid solution can be written as follows



Let's consider the ionization of sulfuric acid as follows


Hydrogen ion has an oxidation number of 1 and sulfate ion has an oxidation number of 2. The number of equivalence of a solute is defined as the product of the number of positive ions in a metal ion and the number of negative ions in a non-metal ion. In this case, the number of equivalence of sulfuric acid is 1 x 2 = 2.

The normality of a solution is defined as the number of equivalence of a solute per liter of solution.

Therefore, the normality of a sulfuric acid solution is
