Question: Which of the following azeotropes is not correctly matched....

Which of the following azeotropes is not correctly matched.

A

HNO3(68%)+H2O(32%):\mathrm { HNO } _ { 3 } ( 68 \% ) + \mathrm { H } _ { 2 } \mathrm { O } ( 32 \% ) : maximum boiling

azeotrope, boiling point =

B

H2O(43%)+HI(57%):\mathrm { H } _ { 2 } \mathrm { O } ( 43 \% ) + \mathrm { HI } ( 57 \% ) : maximum boiling azeotrope, boiling point = 290 K

C

C2H5OH(95.5%)+H2O(4.5%)\mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { OH } ( 95.5 \% ) + \mathrm { H } _ { 2 } \mathrm { O } ( 4.5 \% )maximum

boiling azeotrope, boiling =

D

Chloroform +C2H5OH(6.8%):+ \mathrm { C } _ { 2 } \mathrm { H } _ { 5 } \mathrm { OH } ( 6.8 \% ) : maximum

boiling azeotrope, boiling point =

Answer

H2O(43%)+HI(57%):\mathrm { H } _ { 2 } \mathrm { O } ( 43 \% ) + \mathrm { HI } ( 57 \% ) : maximum boiling azeotrope, boiling point = 290 K

Explanation

Solution

H2O\mathrm { H } _ { 2 } \mathrm { O } (43%) and HI (57%) make maximum boiling azeotropic mixture on boiling at 400K
