3. Color is a chemical property of a pure substance. From your observations of the color changes in the permanganate oxidation of benzaldehyde, make some deductions about the number of chemical species involved and if the organic compounds or the inorganic compounds are responsible for the colors observed.

See explanation

Explanation:

We know that in the presence of strong oxidizing agents such as permanganate , aldehydes are oxidized. This oxidation is often accompanied by a colour change.

The colour change in the permanganate oxidation of benzaldehyde is caused by the inorganic permangate. The colour changes from purple to colourless because Mn^7+ is reduced to Mn^2+.

The benzaldehyde is readily oxidized to benzoic acid in the presence of permanganate.

the answer is true.
