실험 절차

There are three forms of bismuth nitrate, two of which are insoluble in water. One way to obtain soluble bismuth nitrate is to roast the bismuth sulfate first at a low temperature (200° C.) to convert it to the oxide, and then subject the oxide to concentrated nitric acid. The molar ratio of acid to bismuth oxide should be greater than or equal to 4:1 in order to avoid producing insoluble bismuth nitrate. Using this method, the bismuth was completely dissolved. Fine crystals of soluble bismuth nitrate were then formed through evaporation of a majority of the liquor, followed by filtration.
