When considering the chemical structure of these two compounds, calcium hypochlorite contains two hypochlorite anions associated with one calcium cation whereas sodium hypochlorite contains one hypochlorite anion associated with one sodium cation. Moreover, calcium hypochlorite is more stable than sodium hypochlorite.
Should I use calcium hypochlorite or sodium hypochlorite?
When buying disinfectant for your pool, you’ll probably most commonly see cal-hypo. But if you live in a region where calcium deposits are an issue, sodium hypochlorite might be the more effective way to go. Just make sure that you’re testing all your levels frequently and using it with a stabilizer like CYA.
Is calcium hypochlorite the same as bleach?
Sodium and calcium hypochlorite are used primarily as bleaching agents or disinfectants. They are components of commercial bleaches, cleaning solutions, and disinfectants for drinking water and wastewater purification systems and swimming pools.
Why should calcium hypochlorite and sodium hypochlorite never be used together?
Most common swimming pool chemicals are incompatible with each other and should never be mixed. Mixing of organic chlorinating agents (such as trichloroisocyanuric acid) and inorganic chlorinating agents (such as sodium hypochlorite) can lead to fires, explosions and chlorine gas release.
What is calcium hypochlorite used for?
Used for water purification, disinfectant for swimming pools, for bleaching paper and textiles. Calcium hypochlorite is a calcium salt. It has a role as a bleaching agent. It contains a hypochlorite.
Is calcium and sodium hypochlorite the same?
Sodium hypochlorite solutions are clear, greenish to yellow liquids with an odor of chlorine. Calcium hypochlorite is a white solid that readily decomposes in water releasing oxygen and chlorine. It also has a strong chlorine odor. Neither compound occur naturally in the environment.
Can calcium hypochlorite be used as disinfectant?
Calcium hypochlorite may be dosed as a solution into a flow of water at a constant rate (see Fact Sheet 2.22). It can be used for disinfecting installations (see Fact Sheets 2.25 to 2.28).
How much calcium is in calcium hypochlorite?
Commercially available varieties generally contain 65% to 75% chlorine. It also adds around 0.8 parts per million (ppm) of calcium to your pool water for every 1 ppm of free chlorine (FC), or the chlorine actively available to sanitize your pool, you add.
Can calcium hypochlorite be used as bleach?
Sodium and calcium hypochlorite are used primarily as bleaching agents or disinfectants. They are components of commercial bleaches, cleaning solutions, and disinfectants for drinking water and waste water purification systems and swimming pools.
Is calcium hypochlorite chlorine?
Calcium Hypochlorite is commonly seen as granular Chlorine but also is in puck/tablet form. Calcium Hypo has an AC of 40-78% and it the most popular of the Chlorines. Calcium Hypo is used not only to shock a pool but is used in erosion feeders as the main way to disinfect a pool.
How long does calcium hypochlorite last?
Powdered or granulated calcium hypochlorite is an effective option for chlorine disinfection. It has a usable shelf life of up to 10 years.
What happens if you mix calcium hypochlorite with water?
Calcium hypochlorite has the molecular formula of Ca(ClO)2 and a molecular weight of 142.974 g/mol. Its CAS number is 7778-54-3. Its specific gravity is 1.21 g/cm3. When dissolved in water, it can provide nascent chlorine and oxygen to sterilize pool water or industrial wastewater.
Is calcium hypochlorite hazardous?
Both hypochlorites are toxic by the oral and dermal routes and can react to release chlorine or chloramine which can be inhaled. The toxic effects of sodium and calcium hypochlorite are primarily due to the corrosive properties of the hypochlorite moiety.
Can calcium hypochlorite explode?
* Calcium Hypochlorite may ignite or explode on contact with COMBUSTIBLES (such as wood, paper and oil).
