3 NaF NaClNaBrNaI Now add calcium nitrate to each tube

4 Added calcium nitrate to each tube. NaFNaClNaBr NaI

5 Calcium nitrate + sodium fluoride = a precipitate What could it be? Calcium nitrate + NaF === calcium fluoride + sodium nitrate which is the precipitate??? Now balance the equation!

6

7 NaINaBr NaCl NaF Now add silver nitrate to each tube

8 Added silver nitrate to each tube NaINaBr NaClNaF

9 What could be causing the precipitate in the tubes? NaClNaBr NaI Added silver nitrate NaCl + silver nitrate = precipitate NaBr + silver nitrate = precipitate NaI + silver nitrate = precipitate NaCl + silver nitrate = sodium nitrate + silver chloride Which one is the precipitate?

10 1st add ammonium hydroxide to each of the tubes containing precipitates, then later add sodium thiosulfate to each one

11 1. Now add ammonium hydroxide to each tube Now add sodium thiosulfate to each tube. 2.

12 AgCl + ammonium hydroxide = precipitate dissolves…. AgBr + sodium thiosulfate = precipitate dissolves AgI doesnt dissolve with either solution. You can try to predict what the balanced equations might be.
