- Name the process that occurs. Why is it called so?
- Illustrate the reaction of the process with the help of a chemical equation.
A metal nitrate 'A' on heating gives a metal oxide along with evolution of a brown coloured gas 'B' and a colourless gas, which helps in burning. Aqueous solution of 'A' when reacted with potassium iodide forms a yellow precipitate.
