Question

Write the balanced chemical equation for the following:

concentrated Hydrochloric acid and Potassium permanganate solution.

Answer 1

Reaction between concentrated Hydrochloric acid and Potassium permanganate solution:

• When conc. Hydrochloric Acid is added to the Potassium permanganate solution, it will give Manganese chloride, Potassium chloride, water, and Chlorine gas as a product.
• In this reaction, Hydrochloric acid acts as a reducing agent by oxidizing itself to chlorine gas.

Balanced chemical equation :

$\underset{\mathrm{Potassium}\mathrm{permanganate}}{2{\mathrm{KMnO}}_4\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrochloric}\mathrm{acid}}{16\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Potassium}\mathrm{chloride}}{2\mathrm{KCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Manganese}\mathrm{chloride}}{2{\mathrm{MnCl}}_2\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{8{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}+\underset{\mathrm{Chlorine}\mathrm{gas}}{5{\mathrm{Cl}}_2\left(\mathrm{g}\right)}$
