Preparation of chlorine

Example: To make a 0.5% chlorine solution from 3.5% [Footnote 2] bleach: [3.5% ∕ 0.5%] − 1 = 7 − 1 = 6 parts water for each part bleach. Therefore, you must add 1 part 3.5% bleach to 6 parts water to make a 0.5% chlorine solution Preparation Methods. 1) We can prepare the gas by heating manganese dioxide along with concentrated hydrochloric acid. We can also prepare the gas by the activity of hydrochloric acid on bleaching powder (or) lead dioxide potassium (or) permanganate

Chlorine test kits are available to test the level of active chlorine present in a solution. These commonly involve a color change. Some tests employ strips of paper treated with chemicals that change color based on the chlorine concentration and some employ liquid reagents that change color when added to a chlorine solution. In either case Chlorine, along with its important by-product, sodium hydroxide, is produced from the readily available starting material, rock salt (sodium chloride). It is well known for its use in sterilizing drinking water and in particular swimming pool water.
