an acid
well if the PH is above 7 it is a base and if it is below it is an acid... if we swam in swimming pools that were acidic... that would be bad. i don't know about landfill sites...
The common name for HCl when used to lower pH in swimming pools is muriatic acid.
Sodium Bisulphate is dry acid for swimming pool use.
Chlorine.
HOCL or hypochlorus acid
Usually you would add muriatic acid to adjust the pools acid level.
You have to know what you are doing. The addition of muriatic acid lowers the pH and total alkalinity in swimming pools.
Muriatic acid is commonly used in swimming pools to lower the pH levels and alkalinity of the water, which helps prevent the growth of algae and bacteria. It is also used to clean and maintain the pool's surfaces and equipment.
Indoor swimming pools can use bromine. You can't use bromine on outdoor pools because there is no cyanuric acid in bromine. In other words, bromine molecules would have a very short life, almost worthless, in an outdoor pool.
PH levels make sure water is not to acid.
Carbonic Acid, H2CO3 , or acid rain, is derived from rain mixing with the carbon dioxide in the air.
