Osmosis occurs when a solution of low solubility travels to an area of higher solubility. Osmotic pressure occurs when a semipermeable membrane separates two solutions of different solubility; the passage of the solution through the membrane causes pressure against osmosis. The more solution, or ...
The first determinations of osmotic pressures of proteins were made by Starling. He filtered blood serum through a gelatin membrane and obtained a solution that contained the crystalloid constituents of serum but from which the proteins had been withheld. Measurements of the osmotic pressures of the ...
Osmotic pressure of 40% (wt./vol.) urea solution is 1.64 atm and that of 3.42% (wt./vol.) cane sugar is 2.46 atm. When equal volumes of the above two solution

Osmotic Pressure:This is the pressure exerted by the solution. This stops the solvent flow from passing by the way of the semipermeable membrane. This process is also called osmosis.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now Create an...
Osmolality (or osmolarity) should be used instead of osmotic pressure to describe the movement of water between compartments while the use of osmotic pressure should be reserved for situations where filtration and osmosis are operating together. 展开 关键词: solution concentration osmolarity osmolality ...
20. The osmotic pressure of blood at 37 ℃ is 780 kPa, A solution that is given intravenously(由静脉内) must have the same osmotic pressure as the blood. What should be the molarity(物质的量浓度) of a glucose solution to give an osmotic pressure of 780 kP a at 37 ℃. 相关知识点...
Step 5: Calculate the osmotic pressure (π)Now we can substitute C, R, and T into the osmotic pressure formula:π=C⋅R⋅T=0.833 mol/L×0.0821 L⋅atm/(K⋅mol)×273 K Calculating this gives:π≈18.68 atm Final AnswerThus, the osmotic pressure of the 5% solution of urea at 273...
17. Which aqueous solution has the higher osmotic pressure at a given temperature, 10% glucose (CH O ), or 10% sucrose ( C12 H22O1) ? ( Both are molecular compounds. ) 相关知识点: 试题来源: 解析 解:两者都是非电解质,但C H O的摩尔质量小,所以质量相同时,C H O的浓度大,在同样温度 ...
