Prepare a fresh Na Sn(OH), solution by placing 2 drops of 1,0 M Sncly in a small test tube followed by drops of 6 M NaOH until the Sn(OH)2 precipitate just dissolves. Agitate or stir the solution 12. Confirmatory Test. Add several drops of the Na Sn(OH), solution to the precipitate from step 9. The immediate formation of a black precipitate confirms the presence of the Bi3+ ion in the sample.
