Descaling agents

Three subjects who intentionally swallowed between 1 mouthful and 100 ml of descaling agents containing 40 to 55% v/v of formic acid, died 5 to 14 days after ingestion (R. B. Naik et al.. Postgrad, med. J., 1980, 56, 451-456). 

Sodium hypochlorite and chlorine gas are the most common agents for treating the water supply itself, and the concentration employed depends both upon the dwell time and the chlorine demand of the water. For most purposes a free residual chlorine level of 0.5-5 ppm is adequate. For storage vessels, pipelines, pumps and outlets a higher level of 50-100 ppm may be necessary, but it is usually necessary to use a descaling agent before disinfection in areas where the water is hard. Distilled, deionized and RO systems and pipelines may be treated with sodium hypochlorite or 1% formaldehyde solution. With deionized systems it is usual to exhaust the resin beds with brine before sterilization with formaldehyde to prevent its inactivation to...

Acetic acid is one of the simplest carboxylic acids. It is an important chemical reagent and industrial chemical, used in the production of polyethylene terephthalate mainly used in soft drink bottles cellulose acetate, mainly for photographic film and polyvinyl acetate for wood glue, as well as synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is used under the food additive code E260 as an acidity regulator and as a condiment. 

Dilute solutions of acetic acids are also used as a stop bath during the development of photographic films, and in descaling agents to remove limescale from taps and kettles. In the clinical laboratory dilute acetic acid lyse red blood cells in order to facilitate microscopic examination.

This acid is also called aminosulphonic acid. It is a sulphonation agent. It is a strong acid the pH of a solution at 22 g-l is 1.5. It is highly soluble in water 20 g-l at 15 °C and 320g-l at 50 °C. Its solutions are used as a descaling agent, especially in household appliances that heat water, such as electric coffee-makers. 

Glycolic acid CH2OHCOOH is used for dyeing and tannery and as a bactericide or descaling agent.
