Chlorine is toxic to fish. Even at low concentrations, it can damage their gills. An aqueous solution of sodium thiosulfate can be added to tap water to remove dissolved chlorine: 2Na₂S₂O₃(aq) + Cl₂(aq) → 2NaCl(aq) + Na₂S₄O₆(aq). Suppose that you are setting up an aquarium that holds 60 L of water. You use a test strip to estimate that your tap water contains 10 ppm chlorine. You use a chart on the bottle of sodium thiosulfate solution to determine that you should add 60 mL of the solution to the water in the aquarium. If this amount removes all the dissolved chlorine, what is the molar concentration of the sodium thiosulfate solution

Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.
