- To determine the percentage of bromide in a mixture containing a soluble bromide salt, the procedure from Experiment 10 is used except the bromide is precipitated with aqueous lead (II) nitrate, Pb(NO3)2, forming PbBr2(s). Initially, a 0.7893 g sample of an unknown bromide salt is dissolved in water. Excess Pb(NO3)2 is added to the solution to quantitatively precipitate the bromide from the solution. The resulting mixture is filtered through a piece of filter paper weighing 1.3587 g. After several days of drying, the filter paper and precipitate weighed 1.8257 g. Calculate the percent bromide in the original sample. Pb(NO3)2 Mw = 331.2 g/mol PbBr2 Mw = 367.0 g/molIron (II) fluoride needs to be precipitated from a 77.07 L tank.
