An N/50 sulfuric acid solution is also known as what strength?

The strength of an N/50 sulfuric acid solution is 0.02 Normal. Normality (N) expresses the concentration of active equivalents of a solute in a solution. In the case of sulfuric acid (H2SO4), which has two acidic protons (H+), the normality is defined as the number of equivalents of solute per liter of solution.

When a solution is labeled as N/50, it means that one liter of this solution contains 1/50 of a normal solution. A normal solution of sulfuric acid would be 1N, which contains 98 grams of H2SO4 per liter because the molecular weight of sulfuric acid is approximately 98 g/mol. Thus, a 1N solution would provide 2 equivalents of H+, contributing to its normality.

Dividing by 50 yields a concentration of 0.02 equivalents per liter, leading to a corresponding concentration of 0.02 Normal. Therefore, recognizing the conversion from normality to the specific strength of the solution is crucial in understanding the correct answer.
