Sulfuric acid having concentration greater than 98.5% H_2SO_4cannot be – InterviewSolution

1.	Sulfuric acid having concentration greater than 98.5% H_2SO_4cannot be obtained by distillation of an aqueous solution of H_2SO_4. Why?
Answer» SOLUTION :Sulfuric acid having 98.5% `H_2SO_4` FORMS a constant boiling mixture having B.P. of 611 K. Hence, dilute sulfuric acid cannot be CONCENTRATED beyond 98.5% by distillation.
