Which is more effective sodium hypochlorite or calcium hypochlorite?

Which is more effective sodium hypochlorite or calcium hypochlorite?

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.

Can we use calcium hypochlorite instead of sodium hypochlorite?

Calcium hypochlorite is relatively stable and has greater available chlorine than sodium hypochlorite. Calcium hypochlorite can release more OCl- ions and Cl2 gas than sodium hypochlorite.

Can I use calcium hypochlorite in my pool?

High-strength calcium hypochlorite (65 percent) has been widely used as a disinfecting agent in swimming pools and municipal water treatment since 1928. It is a convenient source of available chlorine, one of the most widely used chemicals for disinfecting swimming pool water.

Why is calcium hypochlorite more stable than sodium hypochlorite?

This compound is relatively stable and has greater available chlorine than sodium hypochlorite. It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air….Calcium hypochlorite.

Why is calcium hypochlorite preferred to sodium hypochlorite?

Calcium hypochlorite is more stable than sodium hypochlorite, and contains a higher chlorine concentration (30-75%). Like sodium hypochlorite, calcium hypochlorite also increases water pH, so it is advised to acidify the water during the disinfection process.

Can you mix calcium hypochlorite with sodium hypochlorite in a pool?

Solutions of sodium hypochlorite are commonly referred to as bleach, although household bleach also contains small amounts of several other compounds, including sodium hydroxide and calcium hypochlorite. If these are mixed with bleach, it can react with sodium hypochlorite, and form toxic chlorine gas.

Does calcium hypochlorite affect pool alkalinity?

You also must consider how each sanitizer affects the water’s balance. In addition to raising available chlorine, cal hypo boosts pH, alkalinity and calcium hardness (CH) levels. Trichlor has the opposite effect on pH and alkalinity — reducing it. And where cal hypo affects CH, trichlor increases cyanuric acid (CYA).

Can I use calcium hypochlorite instead of chlorine?

Well, it works just like any other type of chlorine. After adding calcium hypochlorite to your pool, the chlorine quickly reacts with the water to form Hydrochloric Acid.

Is calcium hypochlorite corrosive?

Calcium hypochlorite is a corrosive material with a strong odor. Reactions between calcium hypochlorite and organic material can generate enough heat to cause a fire or explosion.

Is calcium hypochlorite the same as 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. The difference between the Calcium Hypochlorite sold in pool stores versus local mart stores is the AC level.
