Q.

17) In a chemistry laboratory, a research scholar while conducting an experiment, observed at a certain step that yellow coloured gas (X) was released and it has been found to be poisonous. This was later made to react with highly reactive metal (Y). A new compound (Z) was formed which was used for preservation of fish, meat, and pickles. Professor asked him to identify X, Y, and Z.
