Question

Into three of the wells of your well-plate, add a small amount of NaF and 5 drops of deionized water. To the first well, add 5 drops of 2 M Ca(NO)2 and observe any changes. To the second well, add 5 drops of 0.1 M AgNO3 and observe any changes; after about 1 minute add 5 drops of 3 M NH40H and observe any changes. To the third well, add 1 drop of 6 M HNOs followed by 5 drops of 0.1 M Fe(N0 and observe any changes. may take some time to see so be patient when conducting this part of the experiment Repeat this experiment three more times using NacL KBr,and Klinstead of NaE,

Explanation / Answer

2NaF (aq)+ Ca(NO3)2(aq) ----> CaF2(s) + 2NaNO3 (aq)

NaF(aq) + AgNO3 (aq) NaNO3 (aq)+ AgCl(s)

3 NaF(aq) + Fe(NO3)3(aq) FeF3(s) + 3 NaNO3(aq)
