The amount of 13(aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2S₂O3(aq) +13(aq) →S,O2 (aq) +31-(aq) - Given that it requires 27.8 mL of 0.200 M Na₂S₂O3(aq) to titrate a 20.0 mL sample of 13 (aq), calculate the molarity of 15 (aq) in the solution. [13] = M

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.
