Question

1.1 Consider 5 kg (i.e. 5000 g) of chlorobenzene spilled into a container which is completely filled with water (Volume of container = 10000 L) at room temperature (25 0C). Is there enough amount of chlorobenzene to saturate water? Given sufficient time, what would be the concentration of chlorobenzene in water? How much chlorobenzene, if any, will remain as spilled liquid (not dissolved in the water)? (Points: 10)

Answer 1

The solubility o chlorobenzene in water is 0.495 gram per litre.

For 10,000 L, amount of chlorobenzene required = 10000 x 0.495 = 4950 g or 4.95 kg

Thus, the given amount of chlorobenzene is excess.

At very large times, the undissoved chlorobenzene = 50 grams
