Azeotropic mixture of $HCl$ and water has .......... $\%$ $HCl$.

Components of a binary mixture of two liquids $A$ and $B$ were being separated by distillation. After some time,the separation of components stopped and the composition of the vapour phase became the same as that of the liquid phase. Both the components started coming in the distillate. Explain why this happened.

What is the approximate percentage by mass of aqueous $HNO_3$ that can be obtained by distillation (in $\%$)?

Which one of the following is the correct statement? If an azeotropic solution of two liquids has a boiling point higher than both of them,then it:

The process of manufacture of absolute alcohol from rectified spirit is:

When rectified spirit and benzene are distilled together,the first fraction obtained is
