Question

How Can We Prepare Chlorine Water ?

Answer 1

To prepare chlorine water a conducted chlorine gas is passed first through a flask containing a little water, then into a bottle filled with cold water, and continue the process until the fluid is saturated. Where it is desired to obtain chlorine water quite free from bromine, the washing flask is changed after about one-half of the chlorine has been expelled, and the gas which now passes over is conducted into a fresh bottle filled with water. If the chlorine water is to be quite free from hydrochloric acid, the gas must be passed through a U tube containing manganese dioxide. The chlorine water must be protected from the action of light, since, if this precaution is neglected, it speedily suffers complete decomposition, being converted into dilute hydrochloric acid, with evolution of oxygen (resulting from the decomposition of water). Smaller quantities, intended for use in the laboratory, are best kept in a stoppered bottle protected by a case of pasteboard. Chlorine water which has lost its strong peculiar odor is unfit for use.

Answer 2

Answer:

Combine homemade bleach with about 3.5 percent concentrated chlorine as one part in six parts water. This depends on the amount of water you use. Make i. 50 solutions of chlorine using powder bleach (35 percent solution of hypochlorite) by dissolving 14 grams of powder in one liter of water.

Explanation:

The amount of volumes used will vary depending on the concentration of HCl and hypochlorite solutions, but assuming that household bleach is 5% NaOCl and concentrated HCl is 12 M, one adds about 180 mL of bleach indoor and 20 mL of concentrated. HCl up to 800 mL of water to provide about a liter of water chlorine.
