Question

The figure to the right illustrates the 2 phase composition of a mixture of 801 water and phenol. A. (1 pt) Does water and phenol experience mutually attractive or repulsive molecular force interactions? Explain briefly. B. (1 pt) What is the composition in terms of phenol at a temperature of . 20°C for each layer? C. (1 pt) What happens to a mixture that is 0.4 mol fraction as the temperature is raised from 40°C to 70°C? D. (1 pt) What is the consulate temperature? 4 o 40 Two-phase region 0 water phenolphenol

Explanation / Answer

a) water and phenol experiences both attractive and repulsive state at certain critical temperatures

at room temp and high temp they  mix completely, forming a single homogeneous solution. when the temp is reached to a range of 70 they become immisicible solutions.

the hydroxyl group of water may function as both a hydrogen bond donor and acceptor; whereas, an ether oxygen may serve only as an acceptor. The solubility of phenol is due to its greater acidity as well as the pi-electron effect

b) At 5% of phenol in water at 20ºC, homogeneous solution produced due to the less percentage of phenol in water and it is miscible

d) the consulate temp is 68.5
