Question

16.a is the saturated NaCl solution isotonic, hypertonic or hypotonic with blood? Explain. b. If a patient was administered an intravenous dose of this solution, what would happen to their red blood cells? What would be a likely initial symptom of high levels of Na* and CI? C. Read the label on the 0.9 % Sodium Chloride IV solution bag. 1. What is the osmolarity of this solution? Is this solution isotonic, hypertonic or hypotonic? Explain. 2. Is the stated 0.9 % NaCl a % (w/w) or a % (w/v)? Explain. 3. Use the information on the IV bag to calculate the molarity of the NaCl solution Show your work.

Answer 1

16 h Saturated solution is defined as Marimum amount of solute dissolve in solvents leg. waterl we know that hipertonic solution has more solute such as salt I dal dissolved in Solvent water. So, saturated dach Solution is hypertonic with blood. hypotonic solution has lower concentration of solute (e.g salt Calace) dissolved in solvent water. If there is equal amount of solute and solvent in solution than Solution will be isotonic. if a solution has same account of solute leg. salt) present inside and outside of cen, is known as isotonic solution. 6 if a patient was administered with an Solution dose having same amount of solute Present inside and outside of Red blood cells (RBCs) than shape of RBCS

will not change from original shapen - before administration of dose. if solution administered have more Solute concentration than the concentration incide Red blood cells (RBCs) than osmosis process take place to equalize concentrat- ion of solute inside and outside of Cell and so water andres from cel to Solution and share of Cell becomes smaller or cell shrink. So if solution has more Solute concentration than ceus (RBCs) than! RBCS will shrink to smauer shape. When Solution administered have lower solute concentration than the concentration of cells (RBC), osmosis Process take place causing movement of water from solution to Red blood cells (RBCs). Therefore Shape of RBCS will increased or RBCS Swell to larger size than original shape.

There are some initial symptoms OF high levels of Nat and ca. These symptoms are headache, Confusion i nausea, vomiting, Coma etc. we know that tace in aaneous solution dissociate chto teve cous such as dat and .ce- Nace (s - Hat (aa) tał(a.al Osmolarity of any solution is defined as concentration of total ions in solution. For example it concentration TOE dach solution is 5 mol/l I since, tota ions in case solution I is eanan to two (2) so osmolarity of dace solution = 2x molar concentration of dace solution - (2 x 5) Cosmol) = loosmol La osmolanity oF d.gy Solution - 308 mosMIL 0.9.6. Hace solution as (w/v)y.. it

(2.) 0.94. dace Solution is isotonic Solution bcor amount OF Solute and solution inside and outside the cellare same So oogt. Sodium chloride (dace) L is isotonic solution I for oigt. dace solution there is no net Movement of water between Solution and cells y so this solution of dach is isotonic.
