Question

Hydrogen and carbon in organic compounds are tested by heating with copper(II) oxide. $\mathrm{H}_{2} \mathrm{O}$ and $\mathrm{CO}_{2}$ formed are detected respectively, by\

Professor PC Thomas Classes · Answer

$\mathrm{H}_{2} \mathrm{O}$ turns anhydrous $\mathrm{cuSO}_{4}$ blue and $\mathrm{CO}_{2}$ turns time water milky $$ \begin{aligned} & \mathrm{CO}_{2}+\mathrm{Ca}(\mathrm{OH})_{2} \mathrm{caCO}_{3}+\mathrm{H}_{2} \mathrm{O} \ & 5 \mathrm{H}_{2} \mathrm{O}+\mathrm{CuSO}_{4} ightarrow \mathrm{CuSO}_{4} .5 \mathrm{H}_{2} \mathrm{O} \ & \quad(	ext { colourless }) \quad(	ext { blue }) \end{aligned} $$
