Question

ated aqueous solution of urea also contains a significant amount of dissolved carbon dioxide (that is, it is carbonated). What is likely to happen if the solution is cooled?

A saturated aqueous solution of urea also contains a significant amount of dissolved carbon dioxide (that is, it is carbonated). What is likely to happen if the solution is cooled?

Some solid urea will precipitate out of solution. Some carbon dioxide bubbles will be released from the solution and some solid urea will precipitate out of solution. Nothing will happen. Some carbon dioxide bubbles will be released from the solution.

Explanation / Answer

Solution :-

When the urea disolves in water then the solution becomes cold so the dissolution of the urea is endothermic process means it absorbs the heat from water

so if we again cool the solution then some of the urea will reform in the form of precipitate

So the correct answer is option A

that is Some soild urea will precipitate out of solution
