Both of the regular intravenous solutions administeredin medicine, normal saline and lactated Ringer’ssolution, are isotonic. Why is this important?
Isotonic, hypotonic, and hypertonic IV (intravenous) fluid
solutions are widely used in the healthcare setting. As a
possible health care professional, you must know how each of
the solutions work on the body and why they are given.
a) When does each type of solution must be applied to a
patient?
b) What does each type of solution do the cells?
Isotonic IV fluid solution
Hypotonic IV fluid solution
Hypertonic IV fluid solution|
An amino acid mixture consisting of phenylalanine, glycine, and glutamic acid is to be separated by HPLC. The stationary phase is aqueous and the mobile phase is a solvent less polar than water. Which of these amino acids will move the fastest? Which one will move the slowest?

- 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.

It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.arrow_forwardA red blood cell will swell and undergo hemolysis when placed in a hypotonic solution.
