Question

How many statements given below are correct?

1) Sulfate ion gives a white precipitate with lead(II) ion (Pb²⁺), soluble in ammonium acetate due to the formation of $(N H_{4})_{2} [P b (C H_{3} COO)_{4}]$ .

2) PbCl₂ is insoluble in cold water but soluble in hot water.

3) When AgNO₃ reacts with NO₂⁻, a white crystalline precipitate is formed.

4) AgI is insoluble in $N H_{3} (a q)$ solution.

5) Ba gives a yellow-green color in a flame test.

6) Ag₂CO₃ upon heating produces metallic silver.

7) The oxidation state of iron changes from Fe²⁺ to Fe³⁺ in the methylene blue test.
