Is urea soluble in ethanol?

Yes, urea is soluble in ethanol. Urea is a polar compound that forms hydrogen bonds with the polar solvent ethanol, which allows it to dissolve in ethanol.


Why urea solution is not a colloid?

Urea solution is not a colloid because it is a homogeneous mixture where the urea molecules are uniformly dissolved in the solvent, usually water. In a colloid, the particles are not dissolved but are suspended within the solvent, resulting in a heterogeneous mixture.


What are the solvents that dissolve burned urea?

Burned urea, often referred to as urea-derived byproducts or residues, can dissolve in polar solvents. Common solvents that can dissolve these substances include water, methanol, and ethanol. Additionally, some organic solvents like acetone may also be effective, depending on the specific composition of the burned urea residue. However, the effectiveness of the solvent can vary based on the degree of carbonization or other chemical changes the urea has undergone during burning.


A dissolved solute that does not form ions?

A dissolved solute that does not form ions is considered non-electrolyte. Non-electrolytes do not dissociate into ions when dissolved in a solvent. Examples of non-electrolytes include sugar, ethanol, and urea.


Which solutes move the fastest?

Smaller, uncharged solutes like urea and ethanol typically move the fastest through a solvent due to their smaller size and lack of charge. These solutes have lower molecular weight and less interaction with the surrounding solvent molecules, enabling them to move more quickly through a solution.


What is the solvent of urine?

Water is the primary solvent in urine, accounting for about 95% of its composition. Other solutes present in urine include urea, creatinine, uric acid, electrolytes, and various metabolic waste products.


How do you remove excess urea in the body?

Excess urea in the body is primarily removed by the kidneys through urine excretion. Increasing fluid intake can help dilute urea levels and promote its excretion. In severe cases, dialysis may be necessary to remove excess urea from the blood.


What is the organic solvent can use to dissolve urea please urgent?

Urea is a polar molecule that readily / easily dissolves in the polar solvent - water. The term 'organic solvent' is used to describe the more powerful non-polar solvents, such as benzene, or carbon tetrachloride (dry cleaning fluid), that are used to dissolve non-polar compounds.


Is urea soluble in chloroform?

Yes, urea is soluble in chloroform because it is a polar compound and chloroform is a nonpolar solvent. Polar compounds are generally soluble in nonpolar solvents like chloroform.


Why one molal solution of urea is dilute as compare to one molar solution of urea?

A one molal solution of urea contains one mole of urea dissolved in one kilogram of solvent (usually water), while a one molar solution contains one mole of urea dissolved in one liter of solution. Since the density of the solution can vary, a one molal solution typically has a lower concentration of urea in terms of volume compared to a one molar solution, making it more dilute. This is because the molarity takes into account the total volume of the solution, while molality focuses only on the mass of the solvent.


Is dissolution of urea in water endothermic?

Yes. I mean you don't urinate any solids, do you? You may need to heat the water to dissolve urea at a high concentration. The dissolution of urea in water is endothermic (the hot water will cool as urea dissolves!)
