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.
Which solutes diffuse from patient's blood during dialysis?
urea
What materials are removed from the bloods through dialysis?
urea and excess salts
A 5 percent urea solution is hypotonic to a 10 percent urea solution?
true
What substances in the blood pass through the partially permeable membrane into the kidneys?
As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
Why is a dialysis membrane used in a kidney dialysis machine?
A dialysis machine tries to mimic some of the functions of a human kidney. One of the primary jobs of a kidney is to remove urea and certain salts from the blood so they can exit the body in urine. In a dialysis machine, blood from the patient runs through tubes made of a semi-porous membrane. Outside the tubes is a sterile solution made up of water, sugars and other components. Red and white blood cells and other important blood components are too large to fit through the pores in the membranes, but urea and salt flow through membranes into the sterile solution and are removed.
What is boiling point of 1 molar urea solution?
Urea
A dialysis bag is filled with distilled water and then placed in a sucrose solution?
Distilled water will move out of the dialysis bag and into the sucrose solution due to osmosis and the fact that the dialysis bag has a hypertonic solution of H2O as compared to the sucrose solution.
Is urea a base in water but acid in liquid ammonia?
The hydrolysed solution of urea is basic.In liquid ammonia urea act as proton donor and the solution is acidic.
Can urea neutralise pH water?
Urea water solution is neutral.
What is urea N 40?
Usually it means a 40% solution of Urea.
Is aqueous solution of urea an electrolyte?
This solution is not an electrolyte.
