My data to support answers for questions.
The equilibrium is Fe3+ + SCN- <--> [FeSCN]2+. The Fe3+ is a pale yellow colour and the complex ion product is red.
Stresses:
Add KSCN - turned deep red
Add Fe(NO3)3 - turned deep red
Add Na2CO3 - turned yellow/colourless
Add NaOH - turned yellow/colourless
Add NH3 - turned yellow/colourless
Heat - turned lighter orange colour
Cold - turned darker orange colour
Addition of Fe(NO3)3(aq) to test tube #3:
a) what can you infer about the system from the colour change of the solution?
b)How can this be possible if no additional SCN-(aq) has been introduced?
Addition of Na2CO3(s) to test tube #4:
c) As a result of the colour change, what can be concluded about the [FeSCN2+(aq)]? Explain.
d) Explain why the addition of Na2CO3(aq) affects the [FeSCN2+(aq)] as indicated in (a). Use a
