Question

You have a solution that contains the following cations: Ag^+, K^+ and Fe^+3. You first add a few drops of 1 M HCI to the mixture. What will you observe? Include colors and appearance. What cations, if any, will be present in the filtrate? What cations, if any, will be present in the precipitate? After centrifuging and separation of the layers obtained above, you add a few drops of 3 M H_2SO_4 to the liquid obtained above. What will you observe? Include colors and appearance. What cations, if any, will be present in the solution? What cations, if any, will be present in the precipitate? Again, after centrifuging and separation of the layers obtained in step two above, you add 2 M NaOH to the liquid obtained above until the solution is slightly basic, What will you observe? Include colors and appearance. What cations, if any, will be present in the solution? What cations, if any, will be present in the precipitate?

Explanation / Answer

1)

a ) Ag+ ion will precipitate with HCl . white precipitate is formed

Ag+ (aq) + Cl- (aq) ------------------> AgCl(s)

c) K+

3)

a) Fe+3 precipitae as white Fe(OH)3

b) no

c) yes . Fe+3
