Chlorine can be separated from water by allowing the water to sit for a period of time, as chlorine will naturally evaporate. Alternatively, chlorine can be removed by using activated carbon filters or chemical treatment methods such as sodium metabisulfite.
Sodium thiosulfate is used in chlorine removal shampoos because it has a chemical property that allows it to neutralize chlorine. Chlorine can damage hair by stripping it of its natural oils and causing dryness. By adding sodium thiosulfate to shampoo, it can help to break down and remove chlorine from the hair, leaving it clean and less damaged.
To prepare a 0.01N solution of sodium metabisulfite, you would need 2.31 grams of sodium metabisulfite per liter of solution.
2NaHSO3 + Br2 + H2O = NaBr + NaOBr + SO2 + H3O+ I am not happy with this answer - you have a positive charge appearing from nowhere. Also NaHSO3 is sodium bisulfite the questioner asked for sodium metabisulfite which is Na2S2O5 . However, sodium metabisulfite in the presence of water does convert to sodium bisulfite Na2S2O5 + H2O = 2NaHSO3 2NaHSO3 + Br2 + H2O = 2NaBr + H2SO4 + H2SO3
Antimony sulfide; sodium oxide; carbonic acid.
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.
Yes, sodium metabisulfite is commonly used as a fungicide in agriculture to control fungal growth on crops. It works by releasing sulfur dioxide, which inhibits the growth of fungi and prevents decay.

You can research this from the links below (While Sodium Metabisulfite has anti browning properties I am not sure that garlic does!)
You can prevent oxidation of sodium metabisulfite in solution by storing it in a cool, dark place with minimal exposure to air. pH is an important factor in controlling oxidation, as lower pH levels can help stabilize metabisulfite and reduce oxidation. Adding glycerol may not necessarily stop oxidation of metabisulfite, but it could potentially help to slow down the process by acting as a stabilizer.
To neutralize bleach, you can mix it with an equal amount of hydrogen peroxide. The reaction between the two will produce oxygen and water, rendering the bleach ineffective. It's important to handle both chemicals carefully and ensure proper ventilation when neutralizing bleach.
To make a 10% solution of sodium metabisulfite, you would need 10 grams of sodium metabisulfite per 100 ml of solution. If you want to make a larger volume, you would adjust the amount of sodium metabisulfite accordingly.
