Sodium hydroxide solution is added to the solution containing the Fe³⁺ ion.

Match the ions with their coloured precipitate.

Q.

Sodium hydroxide solution is added to the solution containing the Zn²⁺ ion.

Match the ions with their coloured precipitate.

Q. Hydrated salt (A) + $BaC{l}_2⟶$ white ppt (B) insoluble in $HN{O}_3$
(A) (in dil..HCl) + $H_{2}S⟶$ black ppt soluble in 50% $HN{O}_3$
(A) +aq $N{H}_3$ (excess) $⟶$ deep blue solution (C)
(A) +microscomic salt $\underrightarrow{△}$ green (D) when hot
(A) +Kl solution $⟶$ reddish brown changing to white ppt after hypo is added.
2.495 g of (A) gave 2.33 g of (B). Here (A) is identified as $CuS{O}_4.5H_{2}O$.
If true enter 1, else enter 0.

Q. Sodium hydroxide solution is added to the solutions containing the ions mentioned in List X. List Y gives the details of the precipitate. Match the ions with their coloured precipitates.

List X	List Y
(i) Pb2+	(A) Reddish brown
(ii) Fe2+	(B) White insoluble in excess
(iii) Zn2+	(C) Dirty green
(iv) Fe3+	(D) White soluble in excess
(v) Cu2+	(E) White soluble in excess
(vi) Ca2+	(F) Blue

Q. White ppt. in (c) and the soluble complex formed from white ppt. with the hypo solution is/are___________.

Q. (A) gives white ppt with $AgN{O}_3$ soluble in aq $N{H}_3$. (A) gives green ppt (B) with NaOH but ppt dissolves to yellow solution (C) when heated with $H_2{O}_2$. (C) gives yellow ppt (D) with $BaC{l}_2$.
According to above experiment complete the matrix.
