Question

Urea is more soluble in hot water then cold water why?

Answer 1

Because of the high nitrogen concentration in urea, it is very important to achieve an even spread. Urea dissolves in its own weight in water, but becomes increasingly difficult to dissolve as the concentration increases. Dissolving urea in water is endothermic—the solution temperature falls when urea dissolves.Urea is soluble in hot water than cold. Its solubility ratio is 119 grams per 100 grams water at a temperature of 77 degrees Fahrenheit or 25 degrees Celsius.
