In the first step of the process, nickel oxide is reacted with water gas, a mixture of H 2 and CO, at atmospheric pressure and a temperature of 50 °C. The primary use of nickel is in the preparation of alloys such as stainless steel, which accounts for approximately 67% of all nickel used in manufacture.

(This exercise is termed "washing the cyclohexene with water". Transfer the cyclohexene into a clean dry conical flask and add a spatula full of calcium chloride. (Please remember to quickly cover the bottle of calcium carbonate after use since it is hygroscopic and will soon pick up moisture rendering it useless for the rest of the class).

The pH (-\(\log[\ce{H3O+}]\)) of an aqueous solution of an acid (or base) therefore depends on whether it is a strong or weak acid (or base) and, if it is a weak acid (or base), the magnitude of the acid (or base) dissociation constant.

It should be possible to distinguish between the two isomers by considering the immediate environment around the central metal and assuming that their vibrations are independent of the motions involving the rest of the atoms of the ligands.
