What Is The pH Of Calcium Hypochlorite
On the pH of calcium hypochlorite
All things in the world have their own characteristics, and calcium hypochlorite is no exception. Its state in water is related to the change of pH, which is the gist of chemistry.
Calcium hypochlorite dissociates when it enters water. Calcium ions are free in water, and hypochlorite ions meet water as if it were a change of chance. In water, hydrogen ions and hydroxide ions are produced by weak dissociation. Hypochlorite ions and hydrogen ions are affinity, and then hypochlorous acid is formed. During this process, hydroxide ions exist alone in water, resulting in a gradual increase in the concentration of hydroxide ions in water.
According to chemical principles, the pH of a solution is measured by pH value. When the concentration of hydroxide ions increases, the concentration of hydrogen ions decreases relatively, and the solution is alkaline. Therefore, the pH value of calcium hypochlorite solution is greater than 7, showing an alkaline state.
The reason is that hypochlorous acid is a weak acid, and hypochlorite ions have the property of hydrolysis. This hydrolysis process is the source of the alkalinity of the solution. In practical applications, this property cannot be ignored. If it is used for disinfection of water, its alkalinity may affect the state of other substances in the water, which is also related to the effect of disinfection.
Therefore, on the pH value of calcium hypochlorite, it can be known that its solution is alkaline, which is its chemical nature, and it is also the key for users to understand.
