Nitric Acid → Gallium nitrate

A solution of gallium nitrate was prepared as follows: 57.45 parts of gallium were dissolved in 400 ml conc. nitric acid. The mixture was heated until brown fumes appeared, when the heat was removed and the container covered. After standing overnight, the resultant green solution was alternately heated and cooled until it turned yellow, and then clear. Deionized water was added to form 1000 ml of solution.
