There is no such thing.
Liquid household bleach will contain anywhere between 3 and 10 percent chlorine. The powdered form of bleach typically contains 40 percent.
Chlorine is not so much good for swimming but it is good for keeping the water free from harmful microorganisms, economically.
No, swimming in chlorine pools does not prevent fleas on dogs. Also, too much of the chlorine could be harmful to the dog. Try getting some flea prevention from the vet or from the store.
How much acid and chlorine should be added to a 5000 liter to make 5 ppm solution
Yes bleach does contain the same active ingredient as liquid chlorine commonly used in swimming pools but it is at a much lower concentration. Generaly for swimming pools we use either 10% or 12.5% Sodium Hypochlorite.
It is safe. That just means that the chlorine is not actively killing bacteria. It would be unsafe if there was too much chlorine.
Chlorine is not really an allergen (something that causes an allergy), but it is a mild-medium acid, and many people get an itchy rash after being exposed to too much chlorine, e.g. after swimming in a pool just after chlorine has been added. the best way to coulter this us to wash with fresh water wherever you have been exposed to chlorine (like having a shower after swimming)
Chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool.
Do you mean elemental chlorine, or the "chlorine" that's used in swimming pools?Sunlight can break down swimming pool "chlorine". For that matter, it can break down elemental chlorine also, into two chlorine free radicals, which are much more reactive than elemental chlorine (which is, itself, kinda reactive). Sunlight can cause a mixture of elemental chlorine and elemental hydrogen to explode.Free radical chlorine is serious business. It's one of the prime culprits in the degradation of the Earth's ozone layer.
Chlorine is a gas at room temperature. It can be purchased in cylinders for the swimming pool industry. From there it depends on what you call expensive. You can't just go down to the local store and buy it. Solid chlorine would need to be stored at below -34oC . This would be expensive.
It really depends how much liquid you add.
