Question

Write balanced chemical equation of the following

Dehydrating Cane sugar with concentrated sulphuric acid.

Answer 1

The following reaction shows the property of concentrated sulphuric acid as a dehydrating agent. It dehydrates sugar crystals.

• The balanced chemical equation for this reaction is given below.
• $\underset{\mathrm{Sugar}}{{\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\left(\mathrm{s}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{nH}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}\to \underset{\mathrm{Carbon}}{12\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Steam}}{11{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{nH}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}$
• Black spongy charred mass of $\mathrm{Carbon}\left(\mathrm{C}\right)$is obtined and the steam is evolved.
