Question

Write balanced chemical equations to show

The dehydrating property of conc. sulphuric acid with sugar.

Answer 1

1. Sulphuric acid produces sugar charcoal from sugar due to its dehydrating property.
2. When it is added to sugar, water molecules are lost leaving behind charcoal which is chemically carbon.
3. $$\begin{gathered} {\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\stackrel{\mathrm{Conc}.{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }12\mathrm{C}+11{\mathrm{H}}_2\mathrm{O} \\ \left(\mathrm{Sugar}\right)\left(\mathrm{Carbon}\right) \end{gathered}$$
