question_answer 25)

Describe the oxidising action of potassium dichromate and write the ionic equations for its reaction with : (a) iodide (b) iron (iii) solution (c) H2S.

Answer:

On heating with dilute H2SO4, potassium dichromate gives nascent oxygen. Therefore, it behaves as a strong oxidising agent in the presence of dilute sulphuric acid. or         (a)Iodide (b)Iron (II) solution (c)
