In one of the industrial processes used for manufacture of sodium hydroxide, a gas ‘X’ is formed as a by-product. The gas ‘X’ reacts with lime water to give a compound ‘Y’ which is used as a bleaching agent in the chemical industry. Identify ‘X’ and ‘Y’ giving the chemical equations of the reactions involved.

An element A reacts with water to form a compound B which is used in white washing. The compound B on heating forms an oxide C which on treatment with watr gives back B. identify A, B and C and give the reacitons involved.

A water soluble compound 'X' of sodium on reacting with dil. H_2SO_4 released a colourless gas accompanied by brisk effervescence. When the gas was passed through water, the solution obtained turned blue litmus solution red. On bubling the gas through lime water, it initially became milky and the milkness disappeared when the gas was passed in excess. Identify the substance 'X' and write the chemical equation for the reactions involved.

When a metal X is treated with cold water, it gives a basic salt Y with molecular formula XOH (Molecular mass=40) and liberates a gas Z which easily catches fire. Identify X,Y and Z and also write the reaction involved.

Which chemical compound is used for the manufacturing os soaps and also give its commercial name?

A metal carbonate X, and a metal bicarbonate Y on reacting with an acid gives a gas which turns lime water milky. Write the chemical equatins for the reaction of X and Y with the acid.

A substance X used as a antacid reacts with hydrochloric acid to produce a gas Y which is used in fire exitinguishers. Name the substance X and Y.

Iqbal treated a lustrous, divalent element M with sodium hydroxide. He observed the formation of bubbles in reaction mixture. He made the same observations when this element was treated with hydrochloric acid. Suggest how can he identify the produced gas. write the chemical equations for both the reactions.

When electricity is passed through a common salt solution, sodium hydroxide is produced along with the liberation of two gases 'X' and 'Y' The gas X burns with a pop sound whereas 'Y' is used for disinfecting drinking water. Identify X and Y.

A substance X used as a antacid reacts with hydrochloric acid to produce a gas Y which is used in fire exitinguishers. Write a balanced equation of the reaction of X with hydrochloric acid?
