A mixture of sodium bicarbonate and tartaric acid.

Answer 1

• A mixture of sodium bicarbonate and tartaric acid is called Baking powder.
• When sodium bicarbonate reacts with tartaric acid it produces carbon dioxide, sodium hydroxide and hydrogen gas.

$\underset{\mathrm{Sodium}\mathrm{bicarbonate}}{{\mathrm{NaHCO}}_3\left(\mathrm{s}\right)}+\underset{\mathrm{Tartaric}\mathrm{acid}}{{\mathrm{C}}_4{\mathrm{H}}_6{\mathrm{O}}_4\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Carbon}\mathrm{dioxide}}{5{\mathrm{CO}}_2\left(\mathrm{g}\right)(\uparrow )}+\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}}{5{\mathrm{H}}_2\left(\mathrm{g}\right)(\uparrow )}$
