Question

A substance which gives 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

Tardigrade Admin · Accepted Answer

Calcium imparts brick red colour to the flame and calcium nitrate evolves O2 and a brown gas, NO2 upon heating. 2Ca(NO3)2 xrightarrowΔ 2CaO +O2 + underset text(Brown gas)4NO2 uparrow

magnesium nitrate

calcium nitrate

barium nitrate

strontium nitrate

Calcium imparts brick red colour to the flame and calcium nitrate evolves $O_{2}$ and a brown gas, $N O_{2}$ upon heating.
