One question I asked was as below.
A sample of white solid (say 1g) is given. It is known that contains
more than 80% NaCl, and the rest are Na2CO3 and sugar.
Describe a EXPERIMENTAL PROCEDURE with that one may recover NaCl to the highest
purity and yield.
Less than five persons could give some reasonable and useful answers.
How do you think?
