six different aqueous solutions are represented in the beakers below, and there total volumes are noted. (a) which solution has
the highest molarity? (b) which solutions have the same molarity? (c) if you mix solutions A and C, does the resulting solution have a higher molarity then, a lower then, or the same molarity as solution B? (d) after 50.mL of water is added to solution D, is its molarity high than, lower than or the same as the molarity of solution F after 75mL is added to it? (e) how much solvent must be evaporated from the solution of E for it to have the same molarity as solution A?
This question tests your knowledge of the principle of solvent extraction.
In solvent extraction, there is always an organic layer and an aqueous layer. The ethyl acetate is the organic layer while the sodium bicarbonate is the aqueous layer.
A brominated aromatic compound will be extracted into the organic layer (ethyl acetate layer).
