Chemistry Question on Mole concept and Molar Masses
In which of the solutions containing following solutes, its normality is equal to its molarity?
A
Boric acid
B
Sodium carbonate
C
Sulphuric acid
D
Phosphoric acid
Answer
Boric acid
Explanation
Solution
Normality of an acid =basicity × molarity. Boric acid (H3BO3) is a monobasic acid, hence, its basicity is one and therefore, its normality is equal to its molarity.
