6. Explain why the remedy to sever dehydration is not intravenous administration of water. Instead, saline solution (a solution that is isotonic to the liquid inside your cells) must be used for this purpose. Your description must include the terms cell membrane, semi-permeability, diffusion and osmosis. Simple listing of definitions of these terms will not receive credit (5 points)

Medical saline, or saline solution, is used intravenously for many if not most patients admitted to hospitals or who undergo procedures at hospitals. This solution is 0.9 % by mass NaCl. Curiously it does not have a pH of 7.00, as one would expect based on our understanding of acid base phenomena. Using your understanding of Acid-Base, equilibrium, and your soon to be acquired understanding of solubility, please explain, using all appropriate equations, ICE tables etc. the following, explain: What...

The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration. (a) To relieve dehydration, a patient is given 190. mL/h of IV glucose (C6H12O6) for 2.0 h. What mass (g) of glucose did she receive? (b) If isotonic saline (NaCl) is used, what is the molarity of the solution? (c) If the patient is given 160. mL/h of IV saline for 3.0...

The mass of a solute versus the volume of a solution is known as mass/volume percent. It is a unit for concentration (g/L x 100%) often used in medicine, particularly with intravenous (IV) bags. If the mass percent of the saline is 0.9%, how many grams of “salt” are in a 1 L saline IV solution? Show your calculations. Retain all units where appropriate in your calculations. [HINT: 1% is the same as 1 gram in 100ml.]

Sterile normal saline is used in most surgical procedures as an irrigation solution. During certain surgical procedures, such as those for malignancy, the surgeon may request that sterile water be used for irrigation instead of saline following excision of the cancerous mass. 1. What is meant by "normal" saline? 2. Why is normal saline usually used in healthy tissues? 3. How is water different from saline? 4. What reaction will occur between the eukaryotic cells of the body and the...

Perform the following concentration conversions (c) "Normal saline" is an aqueous solution of sodium chloride that is widely used for many medical purposes, manufactured as a sterile solution of 9 grams of NaCl per liter. Calculate the molarity of normal saline. (d) A solution is prepared of 30.0 g of sucrose dissolved in 300.0 mL of water. what is the concentration of this solution expressed as % sucrose by mass? (The density of water is 1.0 g/mL.)

Intravenous, or IV, solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100. mL of solution (sometimes referred to as 0.90% m/v). If the van't Hoff factor of NaCl is ?=1.8, what is the osmotic pressure of blood at body temperature, 37 ∘C?
