White ppt. is produce when $K_{4} [Fe (CN)_{6}]$ solution react with :-

Answer:

Solution:

When K₄[Fe(CN)₆] reacts with CaCl₂(aq.), a white precipitate of Ca₂[Fe(CN)₆] is formed.

$2 C a C l_{2 (a q .)} + K_{4} [F e (CN)_{6}] (a q .) \to C a_{2} [F e (CN)_{6}] (s) + 4 K Cl (a q .)$

CuCl₂ forms a reddish-brown precipitate. SrCl₂ and Na₂SO₄ do not form a precipitate with K₄[Fe(CN)₆].
