Concept explainers
a.
To determine:
The change in red blood cell when it is placed in
Introduction:
Osmosis is a spontaneous flow of solvent from dilute solution into concentrated solution through semi-permeable membrane.
Isotonic solution are those which exerts same osmotic pressure. Hypotonic solution are those which has a lower osmotic pressure than red blood cells and causes flow of water into red blood cells. Hypertonic solution are those which has a higher osmotic pressure than red blood cells and causes shrinking of cell.
b.
To determine:
The change in red blood cell when it is placed in distilled water.

- Specifications for lactated Ringers solution, which is used for intravenous (IV) injections, are as follows to reach 100. mL of solution: 285315 mg Na+ 14.117.3 mg K+ 4.9Q.O mg Ca2+ 368408 mg Cl 231261 mg lactate, C3H5O3 a. Specify the amount of NaCl, KCl, CaCl2 2H2O, and NaC3H5O3 needed to prepare 100. mL lactated Ringers solution. b. What is the range of the osmotic pressure of the solution at 37C, given the preceding specifications?arrow_forwardInsulin is a protein important in the metabolism of sugar. Its molar mass can be determined by means of an osmotic pressure experiment. A 50.0-mg sample of insulin was dissolved in enough water to make 100. mL of solution. This solution was determined to have an osmotic pressure of 21.8 mm H2O. What is the molar mass of insulin? (Hint: The density of mercury is 13.6 g/mL.)arrow_forwardStarch contains CC, CH, CO, and OH bonds. Hydrocarbons have only CC and CH bonds. Both starch and hydrocarbons can form colloidal dispersions in water. Which dispersion is classified as hydrophobic? Which is hydrophilic? Explain briefly.arrow_forward
- How many grams of glucose must be added to 275 g of water in order to prepare each of the following percent-by-mass concentrations of aqueous glucose solution? a. 1.30% b. 5.00% c. 20.0% d. 31.0%arrow_forwardTable sugar (C12H22O11) or urea [(NH2)2CO] can be used by road crews to melt ice on roads, but solutions of CaCl2 are generally used instead. Assuming equal costs per pound of substance, why is CaCl2 used instead of table sugar or urea?arrow_forwardWill red blood cells swell, remain the same size, or shrink when placed in each of the solutions in Problem 8-101? Classify each of the following solutions as hypotonic, isotonic, or hypertonic relative to red blood cells? a. 0.92%(m/v) glucose solution b. 0.92%(m/v) NaCl solution c. 2.3%(m/v) glucose solution d. 5.0%(m/v) NaCl solutionarrow_forward
- You have two aqueous solutions separated by a semipermeable membrane. One contains 5.85 g of NaCl dissolved in 100. mL of solution, and the other contains 8.88 g of KNO3 dissolved in 100. mL of solution. In which direction will solvent flow: from the NaCl solution to the KNO3 solution, or from KNO3 to NaCl? Explain briefly.arrow_forwardConcentrated hydrochloric acid contains 1.00 mol HCl dissolved in 3.31 mol H2O. What is the mole fraction of HCl in concentrated hydrochloric acid? What is the molal concentration of HCl?arrow_forwardCalculate the enthalpies of solution for Li2SO4 and K2SO4. Are the solution processes exothermic or endothermic? Compare them with LiCl and KCl.
