A solution of colourless salt 'S' on boiling with excess NaOH produces – InterviewSolution

1.	A solution of colourless salt 'S' on boiling with excess NaOH produces a non-flammable gas. The evolution of the gas ceases after sometime. Upon addition of Zn dust to the same solution, the gas is evolved again. The colourless salt(s) 'S' can be:
