A substance which gives a brick red flame and breaks down on heating to give oxygen and a brown gas is

A

Magnesium nitrate

B

Calcium nitrate

C

Barium nitrate

D

Strontium nitrate

Text Solution

Verified by Experts

The correct Answer is:
B
Calcium gives brick red coloured flame. Hence, calcium nitrate on heating decomposes into calcium oxide, with evolution of a mixture of `NO_(2)andO_(2)`.
`2Ca(NO_(3))_(2)to2CaO+NO_(2)+O_(2)`
`NO_(2)` is brown coloured gas.
