Electrolysis | Boundless Chemistry - Lumen Learning

In order to predict the products of electrolysis, we first need to understand what electrolysis is and how it works. Electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. It uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction.

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.

Calcium hydride - Wikipedia

2019-4-24 · Calcium hydride is a relatively mild desiccant and, compared to molecular sieves, probably inefficient. Its use is safer than more reactive agents such as sodium metal or sodium-potassium alloy. Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to dry alcohols.
