Question

What is the chemical equation between citric acid and potassium permanganate (write in words)?

Answer 1

Chemical reaction

• A chemical reaction is a process by which one chemical substance changes into another chemical substance.
• For example, iron rusts, coal burns, candles burn, papers burn, milk sets into cottage cheese or ghee, food digests, etc.
• A chemical change occurs during a chemical reaction because a product substance is formed that has entirely different characteristics from the original substance.

Reaction between citric acid and potassium permanganate:

• Citric acid and a purple potassium permanganate solution chemically react, resulting in a colour change from purple to colourless.
• Since it is a reducing agent, citric acid transforms potassium permanganate from purple to colourless.
• Potassium permanganate, a strong oxidizing agent, reacts with citric acid, a weak acid.
• Permanganic acid $\left({\mathrm{HMnO}}_4\right)$ and Potassium isocitrate $\left({\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{K}}_3{\mathrm{O}}_7\right)$ are produced when Citric Acid $\left({\mathrm{C}}_6{\mathrm{H}}_8{\mathrm{O}}_7\right)$ reacts with Potassium Permanganate $\left({\mathrm{KMnO}}_4\right)$.
• The word equation can be depicted as:

$\mathrm{Citric}\mathrm{acid}+\mathrm{Potassium}\mathrm{permanganate}\to \mathrm{Permanganic}\mathrm{acid}+\mathrm{Potassium}\mathrm{isocitrate}$

• The balanced reaction is as follows:

$3{\mathrm{KMnO}}_4\left(\mathrm{aq}\right)+{\mathrm{C}}_6{\mathrm{H}}_8{\mathrm{O}}_7\left(\mathrm{aq}\right)\to 3{\mathrm{HMnO}}_4\left(\mathrm{aq}\right)+{\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{K}}_3{\mathrm{O}}_7\left(\mathrm{aq}\right)$
