Question

Name the gases evolved during the decomposition of lead nitrate

Answer 1

Answer:

Lead nitrate decomposes on heating leaving yellow residue lead monoxide , brown gas nitrogen dioxide and colourless gas oxygen.

Answer 2

Answer:

Lead oxide, nitrogen dioxide, and oxygen are produced as lead nitrate decomposes.

Explanation:

• Lead oxide, nitrogen dioxide, and oxygen are formed when lead nitrate is heated.

• Lead oxide ($PbO$), nitrogen dioxide ($NO_2$), and oxygen are produced when lead nitrate is heated vigorously in a dry test tube ($O_2$).
• Due to the formation of lead oxide ($PbO$), a consequent product, and the generation of nitrogen dioxide, a reddish-brown gas, the lead nitrate seems to turn yellow.

• Decomposition occurs during the heating process of lead nitrate crystals.
• When heated, lead(II) nitrate decomposes into three different colours: brown nitrogen dioxide, colourless oxygen gas, and yellow lead(II) oxide.
