How does chlorine and hypochlorite affect results?

Chlorine as a bleach Chlorine reacts with sodium hydroxide to sodium hypochlorite (NaOCl). This is a very good disinfectant with a stable effect. Bleach cannot be combined with acids. When bleach comes in contact with acids the hypochlorite becomes instable, causing poisonous chlorine gas to escape.

What does hypochlorite do in pools?

The chlorine we think of in connection with summer fun is usually the chemical compound calcium hypochlorite, Ca(OCl)2. Calcium hypochlorite is a white solid that is added in granular or tablet form to pool water to kill germs that can make swimmers sick.

What are the effects of too much chlorine in a pool?

Chlorine, either solid or liquid, is a pesticide used in pools to destroy germs, including those from feces, urine, saliva and other substances. But excessive exposure to chlorine can cause sickness and injuries, including rashes, coughing, nose or throat pain, eye irritation and bouts of asthma, health experts warn.

What is the difference between chlorine and sodium hypochlorite?

The key difference between chlorine and sodium hypochlorite is that the chlorine (Cl2) is a pale yellow color gas whereas the sodium hypochlorite (NaOCl) is a greenish-yellow solid at room temperature. Chlorine and sodium hypochlorite are chemical compounds of the chemical element chlorine (Cl).

Will chlorine raise pH?

Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero).

Can I use sodium hypochlorite in my swimming pool?

In the swimming pool industry one of the most popularly chosen forms for sanitizing water is liquid sodium hypochlorite. Commonly known as liquid chlorine it is widely used in swimming pools both commercial and residential. Also, sodium hypochlorite will not contribute to an increase in calcium or cyanuric acid.

Will sodium hypochlorite kill algae?

In the swimming pool industry, one of the most popularly chosen forms for sanitizing and superchlorinating water is sodium hypochlorite. Sodium hypochlorite effectively destroys bacteria and prevents algae in swimming pools.

How does chlorine increase the pH of a pool?

However, most pools are chlorinated with sodium hypochlorite, which is the conjugate base of hypochlorous acid, one of the acids formed when chlorine reacts with water. Using sodium hypochlorite (which, when in solution, is commonly called “bleach”) will raise the pH of the pool.

What happens when you add calcium hypochlorite to a pool?

After adding calcium hypochlorite to your pool, the chlorine quickly reacts with the water to form Hydrochloric Acid. It’s this acid that attacks and kills the microscopic bad guys floating around.

What happens when you mix chlorine and hypochlorite?

Both chlorine and hypochlorite salts react with water to produce a different compound called hypochlorous acid. This is a relatively weak acid, but also a strong oxidising agent, and actually largely responsible for the bactericidal effects of water chlorination.

What happens when the chlorine level in a swimming pool is too low?

I discuss some of these in the article titled; Maintaining Swimming Pool Chlorine, but here are what you can expect to happen with swimming pool water with a chlorine level that is too low for an extended amount of time: Microbe and bacteria growth. When the chlorine level is too low, microorganisms like bacteria are able to multiply faster.

What’s the relationship between pool chlorine and pH?

Although chlorine is the single most important component in terms of taking care of your pool, it is not independent from the other components of your pool water. The degree to which chlorine is effective in sanitizing your pool by breaking down contaminants is highly correlated to the degree to which pH is kept in balance.

After adding calcium hypochlorite to your pool, the chlorine quickly reacts with the water to form Hydrochloric Acid. It’s this acid that attacks and kills the microscopic bad guys floating around.

What happens when you add organic chlorine to a pool?

Total chlorine is the sum of free and combined chlorine. If organic chlorine (weekly chlorination) is used, cyanuric acid accumulates in the pool. Where the cyanuric acid content is above 100 ppm (mg/l), chlorine blocking may occur, making the chlorine ineffective. Cyanuric acid can be removed by adding water from the mains supply.
