    At room temperature, chlorine is a yellow-green gas that is heavier than air and has a strong irritating odor. It can be converted to a liquid under pressure or cold temperatures. Chlorine is mainly used as bleach in the manufacture of paper and cloth and to make a wide variety of products. Experiment 8: Redox: Analysis of the Oxidizing Capacity of Bleach PURPOSE In this experiment, you will show how redox reactions can be used to quantitatively determine the amount of oxidizing agent in liquid hypochlorite household bleach. There are two oxidation-reduction reactions for determining the oxidizing capacity of bleach.

    Liquid chlorine (bleach) is injected right out of the well, before the pressure tank. Often a contact tank is used to allow sufficient contact time. Typical installation showing chlorine bleach pump injector, on a standard well pump and pressure tank. colored liquid. Liquid chlorine (a liquefied compressed gas) is more economical to ship and store. Other than at large production facilities, liquid chlorine is typically stored and shipped in pound cylinders, 1-ton containers, or and ton tank cars. One volume of liquid chlorine, when vaporized, yields about volumes of gas.

    Test kits shown below are just a sample of the huge number of kits available. If you don't see it listed below, use the Order by Part Number tool at the bottom. Gaseous chlorine is poisonous and classified as a pulmonary irritant. It has intermediate water solubility with the capability of causing acute damage to the upper and lower respiratory tract. Chlorine gas has many industrial uses, but it was also once used as a chemical weapon in World War I. Today, most incidents of chlorine exposure are through accidental industrial or household exposures.

The pH has a significant effect on the stability of sodium hypochlorite solutions. Below pH 11 the decomposition of sodium hypochlorite is significant due to the shift in the equilibrium in favor of the more reactive hypochlorous acid.

A pH between 12 and 13 gives the most stable solution. This equates to to.

Analysis of Commercial Bleach Lab I. Purpose In this experiment, the amount of sodium hypochlorite in a commercial bleach will be determined by reacting it with sodium thiosulfate in the presence of iodide ions and starch.

A solution of sodium thiosulfate of known concentration will be added to the bleach using a buret in a titration procedure. The disappearance of the dark blue color of the.

Chlorine is a chemical element with the symbol Cl and atomic number The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them.

Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron.

Sodium hypochlorite, sodium chlorite and hydrogen peroxide are traditionally used for bleaching cotton and linen products (Sójka-Ledakowicz et al., ).The peroxide method of bleaching does not allow the formation of organic chlorine compounds (AOX), but it does risk damaging.

Uses & Benefits. Chlorine chemistry helps keep families healthy and improves our environment. Water. Chlorine chemistry helps keep drinking water and swimming pools safe. Before cities began routinely treating drinking water with chlorine-based disinfectants, thousands died every year from waterborne diseases such as cholera, typhoid fever, dysentery and hepatitis A.

Chlorine-based pool and. Liquid chlorine shall conform to the following requirements: gaseous impurities content, moisture content, and nonvolatile material content. This abstract is a brief summary of the referenced standard.

3 / Analysis of bleaching powder, calcium hypochlorite T cm bleach liquor, and bleach sludge NOTE 1: Usually for bleaching powder only the percentage of available chlorine is required. However, if desired, the liquid may be analyzed also for total chlorine (see ) and titratable alkali (see ), both as in bleach liquor.

Bleach is the generic name for any chemical product which is used industrially and domestically to clean, and to remove often refers, specifically, to a dilute solution of sodium hypochlorite, also called "liquid bleach".

Many bleaches have broad spectrum bactericidal properties, making them useful for disinfecting and sterilizing and are used in swimming pool sanitation to control.

Chlorine is a very irritating and greenish-yellow gas. It has a strong smell like bleach. It is toxic. It can be made into a liquid when cooled.

It is heavier than air. Chemical properties. Chlorine is highly reactive. It is more reactive than bromine but less reactive than fluorine.

It reacts with most things to make chlorides. It is true that the pH of liquid chlorine is about 13 and bleach is about So adding these will initially raise the pH. However, when chlorine is degraded by sunlight or used in disinfection, the result is that HOCl that becomes HCl and this amount of acid is almost equal to the amount of base (sodium hydroxide) in the liquid chlorine.

Peter Rhys Lewis, Colin Gagg, in Forensic Polymer Engineering, Scanning microscopy. The theory was confirmed by SEM and EDX analysis, large quantities of elemental chlorine being found on the fracture surface. Bleach is usually a strong aqueous solution of sodium hypochlorite, which liberates free chlorine when used, and indeed is the basis of the powerful cleaning action.

Inliquid chlorine (the element in compressed form) became available com-mercially, and in the following year it was employed experimentally for water disinfec-tion in Fort Myer, Va. The chlorine was added to the water by using a simple dry-gas feeder. Inthe first full-scale successful use of liquid chlorine was undertaken to.Sjöström L, Râdeström R, Lindström K Determination of total organic chlorine in spent bleach liquors.
