For the given aqueous reactions, which of the statement (s) is (are) true? For the given aqueous reactions, which of the statement (s) is (are) true?

Options

  1. AThe first reaction is a redox reaction.
  2. BWhite precipitate is Zn3[Fe(CN)6]2\mathrm{Zn}_{3}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]_{2}.
  3. CAddition of filtrate to starch solution gives blue colour.
  4. DWhite precipitate is soluble in NaOH\mathrm{NaOH} solution.

Correct answer

A. The first reaction is a redox reaction.
