In a small jar with a half water inside with liquid dishwashing soap. I dropped a small glob of used oil in the soap a solution. Why is used oil removed when it comes in contact with the detergent? How is the electric nature of colloids exemplified in this activity?

The intracellular salt content of a red blood cell is about 150 mM. The cell is put in a 500 mM salt beaker. (a) Describe what will happen to the cell in terms of osmosis if the cell membrane is permeable to water but not to ions. (b) Which direction would solutes diff use if the membrane was permeable to ions: into or out of the cell?
The simple form of |Hoff equation is: II = [B]RT In this equation the [B] is the molar concentration of solute. So: n m [B] = v MV = cg /MA Where c, the mass concentration of the solute is in the total volume of solution and M, is the molar mass of the solute. This equation can be replaced in the previous one to get: RT II = MA In this equation molar mass of given solute can be detemined from the slope of the II vs Cz plot. This equation applies only to solutions that are sufficiently dilute to behave as ideal-dilute solutions. In the case of non-ideal solutions, however, the extended formula is: II = [B]RT{1+ k. [B] + n. [B]² + ...} Biological macromolecules dissolve to produce solutions that are far from ideal, but we can still calculate the osmotic pressure by assuming that the van't Hoff equation is only the first term of a lengthier expression: II [B]RT(1+ b. [B]) II = RT + bRT. [B] [B] II = RT + bRT./M. */Ma п RT ÞRT Ca MA MA In this equation molar mass of given biomolecule can…
In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution. (b) Identify the osmolarity of the apple.

Consider a solute having a permeability coefficient of 10-6 m s-1 for the plasma membrane of a cylindrical Chara cell that is 100 mm long and 1 mm in diameter. Assume that its concentration remains essentially uniform within the cell. Untitled Title A. How much time would it take for 90% of the solute to diffuse out into a large external solution initially devoid of that substance?* B. How much time would it take if diffusion occurred only at the two ends of the cell?* C. How would the times calculated in A and B change for 99% of the solute to diffuse out? D. How would the times change if Pj were 10-8 m s-1?*
In medical industry, Medical devices use adhesives as one example of application of Intermolecular Forces of Attraction. Adhesives are used extensively in th medical world, from simple plasters to advanced medical applications. Adhesives are integral to the production of paper tissues and nappies, allow tablets to be protected from the effects of moisture and allow wounds to be dressed. Trans dermal patches, such as nicotine patch, permit a controlled delivery of nicotine into the bloodstream to help smokers quit. What are other line of work that applies the Intermolecular forces of Attraction. At least one example and its use in the certain field of work.
