Identify the following substances: An acidic gas which gives dense white fumes with NH_3 .

Identify the following substances : An alkaline gas A which gives dense white fumes with hydrogen chloride.

Name :An alkaline gas .X. which gives dense oxide fumes with HCl.

(i) You are provided with two test tubes containing an aqueous solution of carbonateand sulphite respectively. How will you identify them? (ii) A colourless salt on heating, forms a white sublimate on the cooler sides of the lost tube. The gas evolved is colourless and has a pungent smell. It givos donse white fumes when a rod dipped in conc. HCl is brought near the mouth of the fest tube. Identify the basic radical present in the salt.

Identify the substances which are underlined: An ul("acidic gas") which gives dense white fumes with NH_3

A gas 'X' combines with another gas 'Y' in the presence of a catalyst 'C' to form a colourless gas 'Z'. The gas Z gives dense white fumes with hydrogen chloride and the gas 'Y' turns red litmus blue. Name the catalyst C.

A gas 'X' combines with another gas 'Y' in the presence of a catalyst 'C' to form a colourless gas 'Z'. The gas Z gives dense white fumes with hydrogen chloride and turns red litmus blue. Write a balanced chemical equation for the formation of Z.
