When you add copper sulfate to a urea solution, a chemical reaction occurs that results in the formation of a complex between the copper ions in copper sulfate and urea molecules. This complexation reaction can lead to the precipitation of copper hydroxide if the pH of the solution is high.
No, an aqueous solution of urea does not conduct electricity because urea molecules do not dissociate into ions in water. Therefore, it is a non-electrolyte solution.
Oh, dude, that's an easy one. A mixture of urea and water is called a solution. It's like when you mix sugar in your coffee - it's all dissolved and blended together. So yeah, it's just a fancy way of saying urea and water hanging out together.
The concentration of the solution is calculated by dividing the mass of solute (urea) by the total mass of the solution and then multiplying by 100%. In this case, the concentration of the solution containing 16g of urea in 120g of solution would be 16g / 120g * 100% = 13.3%.
The pH of a freshly prepared solution of urea is around 7, which is considered neutral. However, urea can hydrolyze over time to form ammonia and carbon dioxide, which can increase the pH of the solution.
The boiling point of a 1 molar urea solution will be higher than the boiling point of pure water. Urea is a non-volatile solute that raises the boiling point of the solution through boiling point elevation. The exact boiling point elevation can be calculated using the formula: ΔTb = i * K_b * m, where i is the van't Hoff factor (1 for urea), K_b is the ebullioscopic constant of the solvent (water), and m is the molality of the solution.
Copper sulfate solution provides cupric ions that react with the peptide bonds present in the protein molecule. The test is called as biuret test, as it was originally given by biuret compound.( when urea is heated it forms biuret). The reaction is due to the formation of complex between the cupric ions and lone pair of electrons present on the Nitrogen and Oxygen atoms of peptide bond.
true
The isotonic solution for Urea would be a solution that has the same osmotic pressure as a cell. This concentration would typically be around 0.15 M for Urea.
Ammonium sulfate is not a slow release fertilizer.Specifically, ammonium nitrate, ammonium sulfate, liquid nitrate, urea and urea-ammonium are quick release forms of nitrogen fertilizer. They are soluble. They tend to solve lawn problems, as do the slow releasing natural organics, polymer and sulphur coasted urea, and urea-formaldehyde.
No, an aqueous solution of urea does not conduct electricity because urea molecules do not dissociate into ions in water. Therefore, it is a non-electrolyte solution.
The hydrolysed solution of urea is basic.In liquid ammonia urea act as proton donor and the solution is acidic.
Usually it means a 40% solution of Urea.
Urea water solution is neutral.
This solution is not an electrolyte.
