PCAT Chemical Processes – Acid Normality

What is the normality of a 0.75 M H2SO4 solution?

A. 0.375 N
B. 0.75 N
C. 1.5 N
D. 2.25 N

Click for Explanation

C is correct. When dealing with acids, normality is defined as the number of moles of protons per liter of solution. Here, normality can be calculated by multiplying the molarity of the solution (0.75 M) by the number of protons per molecule of H2SO4 (2). This yields an answer of 1.5 N.
