A highly specific maximum boiling azeotrope is formed industrially by an aqueous solution of nitric — Solutions and Colligative Properties Chemistry Question
Question
A highly specific maximum boiling azeotrope is formed industrially by an aqueous solution of nitric acid ($HNO_3$). If the exact literature composition of this azeotrope is precisely $68\%$ $HNO_3$ by mass, what is the exact mass percentage of water ($H_2O$) required in this constant-boiling mixture?
Answer: 32
💡 Solution & Explanation
A binary azeotropic mixture consists entirely of two components. If the mixture is $68\%$ nitric acid by mass, the remaining mass must account for the water solvent. Mass percent of water = $100\% - 68\% = 32\%$.
