Electrolytic Cells - chemed.chem.purdue.edu

The potential required to oxidize Cl-ions to Cl 2 is -1.36 volts and the potential needed to reduce Na + ions to sodium metal is -2.71 volts. The battery used to drive this reaction must therefore have a potential of at least 4.07 volts. This example explains why the process is called electrolysis.The suffix -lysis comes from the Greek stem meaning to loosen or split up.

2018-3-6 · Find the mole fraction of water in a solution prepared by dissolving 4.50 g of CaBr 2 in 84.0 mL of water. Solution: The molar mass of CaBr 2 is 200 g, and 84.0 mL of H 2 O has a mass of very close to 84.0 g at its assumed density of 1.00 g mL –1. Thus the nuer of moles of CaBr 2 in the solution is (4.50 g) / (200 g/mol) = .0225 mol.
