Complete the extraction scheme for the separation of 1,2-dichlorobenzene, phenol (pka = 10), and pyridine. 2. sodium bicarbonate (nahco3) can be used as a base to extract carboxylic acids into the aqueous layer, but it cannot be used to extract most alcohols. explain. 3. explain the difference between extraction and washing. 4. look up the densities and miscibility of hexane and water. see the miscibility chart from experiment 2. would these two solvents work well together in an extraction procedure? explain. cl cl oh n in ether add naoh(aq) aqueous soln: ether soln: acidify with hcl add hcl(aq) aqueous soln: ether soln: basify with naoh component c extract into ether component a component b

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
