What else can I help you with?
How you can determine urea concentration by classical titration?
use the non aqueous titration dissolved urea in glacial acetic acid, and titrate with standard 0.1 mol/L trifluoromethanesulfonic acid in acetic acid using isobutyl vinyl ether as a thermometric endpoint indicator
Is aqueous solution of urea a conductor?
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.
What is The percentage of nitrogen in urea?
Urea is typically 45-46% nitrogen.
What is mixture of urea and water called?
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.
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!)
What is the isotonic solution for Urea?
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.
Which part of the nephron contains lowest concentration of urea?
filtration
Is urea osmotically active?
Yes, urea is considered to be osmotically active. It can contribute to the osmotic pressure of a solution by attracting water molecules and affecting the overall concentration of solutes.
What in urine?
Urine is a solution of metabolic wastes that contains urea, salts, and many different organic compounds.
How you can determine urea concentration by classical titration?
use the non aqueous titration dissolved urea in glacial acetic acid, and titrate with standard 0.1 mol/L trifluoromethanesulfonic acid in acetic acid using isobutyl vinyl ether as a thermometric endpoint indicator
Which structure contains the hihest concentration of urea in humans?
The bladder, depending on the amount of water in your body. The kidneys filter urea and other waste products out of the blood and send them down the ureter to the bladder in the form of urine. Kidneys dont have the greatest concentration as the urea moves continuously through the loop of henle and into the bladder where it is collected.
A 5 percent urea solution is hypotonic to a 10 percent urea solution?
true
Why does the red blood cell lyse in an isosmotic solution of urea?
Urea is isosmotic to the intracellular fluid of red blood cells, but because the membranes of the blood cells are permeable to urea. Urea enters the cell at a much more rapid rate than other permeable solutes (because of the steep concentration gradient) and the cell fills to it bursts.
Why is it important that the concentration of urea is kept very low in the dialysis fluid?
the concentration of urea should be kept low in the dialysis fluid because urea is harmful for our body if it is not removed.
What would happen to the intracellular and extracellular concentration of urea if the kidney stopped functioning?
If the kidney stopped functioning, the intracellular concentration of urea would increase due to impaired excretion. In contrast, the extracellular concentration of urea would also increase due to the diminished clearance of urea from the blood.
Why urea passes from blood into dialyzing solution?
It works much like your real kidneys. Your kidneys work essentially with a "Salt imbalance". One half of a kidney has a higher saline content than the other half; when blood passes through, urea is "pulled" into the saltier side.
Is aqueous solution of urea a conductor?
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.
