Urea will remain urea after dissolution in water

It will become NH4 when dissolved in water.

No it will not be converted into NH4 since it is organic compound having covalent bond which is difficult to break in water. There is no enzyme in water which may convert it. It is assimilated as such in plant during fertigation in NH2 form

remains Urea

the urea molecule remains intact, just solvated. Urea can be hydrolyzed to bicarbonate and ammonia, but this does not happen at physiological pH, except in our gut, where bacteria have the enzyme urease to catalyze this reaction. (Google)

Mr subhan

Urea, being a molecular substance, does not dissociate into ions. The dissolution process involves adding energy to break the attractive forces between the molecules in the solid structure and releasing energy as the molecules form new attractive forces with the water molecules surrounding it. These attractive forces are called intermolecular forces, which are weaker than the covalent bonds between the atoms within the molecule.

This dissolution process is a physical reaction (or physical change) as opposed to being a chemical reaction (or chemical change) as the chemical composition of urea remains unchanged. To keep it simple, we will refer to it as simply “reaction” but keep in mind it is a physical reaction as shown in Equation 1 below.

CO(NH2)2 (s) CO(NH2)2 (aq)

I hope ur question is answered

Interesting!

Thanks everybody for your answers. Meanwhile I also studied about this. Muhammad Rashid Emohamed Maryol You are right. Urea remains urea, it only dissociates in the presence of some enzymes.

When urea is mixed with water this creates a cold (endothermic) reaction.

• In the field while sowing crop, it needs to be spread. On addition to the soil, urea dissolves into the soil solution and supplies ammonium form of N, but it is rapidly converted to nitrate in the soil. During this process, hydrogen is released which increases soil acidity.

Muhammad Rashid , What is the best method or additive to maximize the cooling endothermic effect of UREA and Water, Can I add a chemical that will increase its endothermic potential? I want to improve the energy absorption and the rate of absorption in water.

Water dissolve urea will won't transform, It will as such remain in urea form.
