Question

When a strip of Metallic Zn is placed in an aqueous solution of copper nitrate the blue colour of the solution disappears due to formation of

Answer 1

Answer:

Zinc nitrate

Explanation:

Zn + Cu(NO₃)₂ → Zn(NO₃)₂ + Cu

Hope this helps.

Answer 2

When a strip of Metallic Zn is placed in an aqueous solution of copper nitrate the blue color of the solution disappears due to the formation of Zinc nitrate.

• The Blue color in the solution was there earlier because of the Cu+2 ion.
• When zinc reacts with copper nitrate zinc nitrate along with copper is formed due to which the blue color of the solution disappeared.
• The strip of metallic Zinc is coated with reddish copper.
• After the reaction, the oxidation state of Cu becomes 0 from +2 which is also responsible for the vanishing of the blue color.

Hence, when a strip of Metallic Zn is placed in an aqueous solution of copper nitrate the blue color of the solution disappears due to the formation of Zinc nitrate.
