10. The gravimetric determination of nickel in alloys Gravimetric analyses belong to the most precise‚ because contemporary analytical balances make possible determination of the mass of a sample with great accuracy. In these analyses one should obtain high purity compound of the analyzed element or a compound directly obtained from the analyzed substance). This reaction has to be exactly stoichiometric. It is also important that the weighed compound was non-hydroscopic and stable in air‚ it also

It has corrosion resistance to mild-atmospheric and fresh water‚ industrial atmospheric‚ marine atmospheric‚ mild chemical and oxidizing chemical environments.

Reverse of a wartime nickel‚ with the mintmark located above Monticello Due to a shortage of nickel during World War II‚ the composition of the five-cent coin was changed to include silver.
