Lab Report #1 Two Base Extraction - Google Docs

Experimental Flow Chart: ... The bicarbonate solution extracted the stronger base because the reaction was favored with benzoic acid, but the base was not strong enough to extract the 2-naphthol. Then the 2-naphthol was able to be extracted from the solution by hydroxide because the pKa of the conjugate acid of hydroxide is water, with a pKa of 15.7. This reaction also heavily favored the ...
