DESCRIPTION

Calcium Hypochlorite is a chemical compound with formula Ca(ClO)2it is a a strong oxidizing agent.As a mixture with lime and calcium chloride, it is marketed as chlorine powder or bleach powder for water treatment and as a bleaching agent. This compound is relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). It is a white solid and strongly smells of chlorine, owing to its slow decomposition in moist air. It is not highly soluble in water and is more preferably used in soft to medium-hard water

Application

Sanitation Calcium Hypochlorite contains approximately 65 percent chlorine as compared to the 12 percent that is typical in liquid bleach. Bleach breaks down over time, losing its strength and efficacy as well as adding to the total dissolved solids in the pool. Calcium Hypochlorite has a neutral pH that can reduce the need for auxiliary treatment chemical. Oxidizing Agent Calcium Hypochlorite is a powerful oxidizing agent, particularly in the presence of water or at higher temperature as Calcium hypochlorite decomposes to release oxygen and chlorine gases. As strong oxidant Calcium hypochlorite may react with vigor in combination with carbon, especially finely divided is explosive; acetylene, leads to creation of explosive chloroacetylenes; organic matter, oil, hydrocarbons; alcohols may cause explosion, methanol, ethanol, etc.; nitromethane caused delayed violent reaction; organic sulfur compounds, sulfides tend toward ignition and sometimes explosion; with iron oxide in metal containers catalyze oxygen evolving decomposition of the oxidant. Calcium hypochlorite forms highly explosive NCl3 on contact with urea .
