Question

Note to moderator: Read the answerline carefully. Entrainers that produce azeotropes (“AY-zee-oh-tropes”) with this property can be easily removed because they uniquely cross residue curve separatrices (“SEP-uh-RAY-triss-iz”). The condensation of a product with this property is essential to the function of a Dean–Stark apparatus, which is why it cannot be used to distill (10[1])ethanol. Binary azeotropes with this property are guaranteed to be minimum-boiling. Materials with low melting points and this property will form slag during smelting. Systems with this property will spontaneously decompose because they lie inside a namesake (-5[1])“gap” bounded by the spinodal (“spy-NODE-al”) curve. (-5[3])Systems with this property can (10[1])be separated (10[1])by decanting, (10[1])which is used to isolate (10[2])organics from the aqueous phase after (10[2])extraction. (-5[1])For 10 points, name this (10[1])property of mixtures (10[2]-5[1])that cannot (10[2])form a single continuous phase. (10[1])■END■ (10[7]0[6])
