Caffeine is about 10 times as soluble in hot water as in cold water. a chemist puts a hot-water extract of caffeine into an ice bath, and some caffeine crystallizes. is the remaining solution saturated, unsaturated, or supersaturated and why?

Supersaturated solution

Explanation:

A super-saturated solution is on that contains more than the amount of solute needed to saturate it at a particular temperature.

In our problem, Caffeine solution was saturated when it was in hot water because it was at a temperature where the solubility is high. Immediately it was introduced to an ice bath, a new temperature is recorded. At that lower temperature only a very less amount of caffeine is needed to saturate the solution, hence the excess crystallizes out and makes the solution super-saturated

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

i think its 5049.

i hope this !
