When a small amount of hexanoic acid [CH₃(CH₂)₄CO₂H,pK_a~4.8],is added to a separatory funnel which contains the organic solvent diethyl ether and water with a pH of 12.0,it is found mainly in the ________ phase as ________.

Question

Quizplus · Accepted Answer

At a pH of 12.0, which is significantly higher than the pKa of hexanoic acid (~4.8), the acid will be deprotonated to form its conjugate base, making it more soluble in water. Therefore, it will be found mainly in the water phase as its deprotonated form.
