How good are you at cristallizing?
This is the task:
Materials:
(approx 1M in 100ml)
KOH (5.6gr)
NaOH (4gr)
KCl (7.5gr) - as dry as possible
NaCl (5.8gr) - as dry as possible
100ml dH2O
Test the ph of chlorides if neutral
Test the hidroxides for chlorides with silver nitrate.
Make a solution by adding the 4 salts into 100 ml dH2O.
Stirr until disolved.
Try to get the salts back.
Test the ph of chlorides if neutral
Test the hidroxides for chlorides with silver nitrate.
1) How will you proceed with this task?
2) Its possible to get the original ammounts of salts? or maybe they rearrange by for example producing more hidroxide than chloride...
Go SAFE, because stupidity and bad Luck exist.

https://www.sciencemadness.org/whisper/viewthread.php?tid=15... would be a good read.
Separating the cations will be difficult
Seperation of the anions can be done with proper solvent selection. Check the solubility against things like acetone, ethonol and Isopropyl alcohol.
