The azeotropic mixture of $HCl$ and water contains ...... $\%$ $HCl$.

The boiling point of an azeotropic mixture of water-ethanol is less than that of both water and ethanol. Then

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

An azeotropic solution of two liquids is one that:

The azeotropic mixture of water $(b.p. \ 100 \ ^oC)$ and $HCl$ $(b.p. \ 85 \ ^oC)$ boils at $108.5 \ ^oC$. When this mixture is distilled,it is possible to obtain:

Dilute hydrochloric acid cannot be concentrated beyond which of the following concentrations by boiling (in $\%$)?
