Fish Microbiology and Quality Assurance 19. Determination. Current Technology of Chlorine Analysis for Water and Wastewater Technical Information Series — Booklet No.17 By Danial L. Harp Lit. no. 7019 L21.5 Printed in U.S.A., Commercial bleaching powder contains 36-38 per cent of available chlorine. Two methods are in common use for the determination of the available chlorine. In the first, the hypochlorite solution or suspension is treated with an excess of a solution of potassium iodide, and strongly acidified with acetic acid: ClO- + 2I- + 2H+ = Cl- + I2 + H2O The liberated iodine is titrated with standard.

1. Available chlorine is the amount of chlorine liberated by the action of dilute mineral acids on bleaching powder. 2. The titration in which liberated iodine is titrated against standard solution of sodium thiosulphate is called iodometric titration. Method of determination of chlorine in bleaching powder General Discussion Most hypochlorites are normally obtained only in solution, but calcium hypochlorite exists in the solid form in commercial bleaching powder which consists essentially of a mixture of calcium hypochlorite Ca(OCl)2 and the basic chloride CaCl2,Ca(OH)2,H2O; some free slaked lime is usually present.

One gram of a 100% active chlorine bleach has the same bleaching power as one gram of chlorine.

Chlorine is available in various forms, including calcium hypochlorite, sodium hypochlorite and as pure chlorine gas in cylinders. Calcium hypochlorite (chlorinated lime, tropical bleach, bleaching powder, ‘HTH’) is a powder Method of determination of chlorine in bleaching powder General Discussion Most hypochlorites are normally obtained only in solution, but calcium hypochlorite exists in the solid form in commercial bleaching powder which consists essentially of a mixture of calcium hypochlorite Ca(OCl)2 and the basic chloride CaCl2,Ca(OH)2,H2O; some free slaked lime is usually present.

Determination of available chlorine in hypochlorite solutions by direct titration with sodium thiosulfate Because most normal household bleach has 5% available chlorine, a 1:10 dilution (or 1 part bleach to 9 parts water, the commonly interpreted "10% bleach solution") is actually a 0.5% hypochlorite (bleach) solution. My guess is the 10% solution you are looking for is 1 part bleach to 9 parts water as this is a very good disinfectant (as long as you remove organic matter with soap and water
