Bleach is a common name that refers to the solution of 2.5 percent sodium hypochlorite in water. It is called liquid or chlorine bleach.
There is a third form of bleach that is peroxide or oxygen-based that you can find out there. Many people know this product is used to remove stains and disinfect, but it can be used for other purposes like shocking a pool.
Today I will help you to understand this product better.
What is Chlorine Bleach? What is Liquid Bleach?
Chlorine bleach is “just chlorine” that you can use to shock your pool – above ground pools or inground pools and remove germs. Liquid bleach is safe and mild chlorine bleach that you can use for all-surface and all-purpose cleaning.

Chemically, chlorine bleach is a solution of sodium hypochlorite and water. The normal bleach is about 6% sodium hypochlorite or 5.25% regular strength.
Types of Bleach
There are different kinds of bleach out there:
- Oxygen bleach that contains peroxide-releasing compound like sodium percarbonate or sodium perborate or hydrogen peroxide
- Bleaching powder which is calcium hypochlorite
- Chlorine bleach which contains sodium hypochlorite
Other bleaching materials include sodium per silicate, sodium pyrophosphate, sodium persulfate, their ammonium, lithium and potassium analogs. Also bromate, chlorine dioxide, organic peroxides, and carbamide peroxide.
How Bleach Works
The oxidizing bleach breaks the chemical bond of a molecule or chromophore. That means that the molecule loses color or shows the color of the surface it is on.
The reducing bleach changes the double bonds of the molecule. That alters the property of the molecule to make it colorless.
At What Temperature Does Bleach Freeze?
Bleach can easily freeze if you leave it outside during the cold months. As noted, there are different types of bleach out there, and each one has its unique freezing point.
With that said, the chlorine content of this product determines at the level it will freeze. For instance, liquid bleach often freezes at a temperature of 19 degrees F. However, that might not occur if your product is inside a protective structure.
Pure chlorine has a freezing point of – 101.5 degrees F, and thus, bleach freezing point will depend on its content.
Liquid Bleach Vs. Chlorine
Although most pool owners like to use chlorine, liquid bleach can also be effective when cleaning their pools. These products are different in these ways:
- Effectiveness – Both bleach and chlorine have calcium hypochlorite chlorine that acts as a disinfectant. There is 5.25% of chlorine in bleach and 65% in normal chlorine. That means that chlorine can clean better if you want instant results.
- Price – Chlorine is more expensive than bleach. Even if you use a lot of bleach in your pool, it will still be cost-effective. That is the main reason why people use bleach for their pools.
- Convenience – Chlorine is hander to mix compared to bleach. You only need to measure the amount of bleach to add and then pour it inside.
Bleach does freeze if left outside during the cold months for a long time. It does the same work as chlorine, but you would require more since it is less concentrated.
