Chlorine itself is rarely used as a disinfectant in swimming pools; generally are used other chemicals as sodium hypochlorite (NaClO), etc.
Dissolved in water sodium hypochlorite release chlorine; and consequently gaseous chlorine exist as a solute in water.
The liquid chlorine formula used for swimming pool maintenance is typically sodium hypochlorite (NaClO).
The liquid is called Chlorine.
There is no such thing.
You can find chlorine in household bleach, swimming pool supplies, and in some cleaning products. Chlorine can also be sourced from commercial suppliers in the form of chlorine gas or liquid chlorine.
It is generally safe to swim in a pool after adding liquid chlorine once the chlorine levels have dropped to recommended levels for swimming, which typically takes about 30 minutes to 1 hour. It is important to test the chlorine levels before entering the pool to ensure it is safe for swimming.
To shock a pool with liquid chlorine effectively, first test the water to ensure the pH and chlorine levels are balanced. Then, pour the recommended amount of liquid chlorine into the pool while the filtration system is running. Allow the chlorine to circulate for several hours before swimming. Remember to follow the manufacturer's instructions and safety precautions when handling and using liquid chlorine.
