Amount of oxalic acid present in a solution can be determined by its titration with ${\text{KMnO}}_4$ solution in the presence of ${\text{H}}_2{\text{SO}}_4$. The titration gives unsatisfactory results when carried out in the presence of $\text{HCl}$ because $\text{HCl}$:

The vapour pressure of water at $20^{\circ }\text{C}$ is $17.5\text{mm Hg}$. If $18\text{g}$ of glucose (${\text{C}}_6{\text{H}}_{12}{\text{O}}_6$) is added to $178.2\text{g}$ of water at $20^{\circ }\text{C}$, the vapour pressure of the resulting solution will be:

Among the following substituted silanes, the one which will give rise to cross-linked silicone polymer on hydrolysis is:

In context with the industrial preparation of hydrogen from water gas ($\text{CO}+{\text{H}}_2$), which of the following is the correct statement?

In a compound, atoms of element $\text{Y}$ form ccp lattice and those of element $\text{X}$ occupy $2/3$ rd of tetrahedral voids. The formula of the compound will be:
