Question
Aqueous hydrochloric acid was used after the sodium bicarbonate and sodium hydroxide extractions in the separation scheme shown in Figure 12.10. Is it possible to use this reagent earlier in the separation scheme to achieve the same overall result? If so, explain where you would perform this extraction.
