• solution d: 6.97% (m/v) glucose
• solution e: 5.0% (m/v) glucose and 0.9%(m/v) nacl

place each solution into the appropriate bin.

crenation hemolysis neither
clear all
check answer
thats incorrect.
either a 0.9% nacl solution or a 5.0% glucose solution would be isotonic, but a 0.9% nacl and 5.0% glucose solution behaves like a solution with a higher solute concentration than blood.

Explanation:

Step1: Recall tonicity concepts

Isotonic solutions have the same solute - concentration as body fluids. Hypertonic solutions have a higher solute - concentration, and hypotonic solutions have a lower solute - concentration. Crenation occurs in hypertonic solutions, hemolysis in hypotonic solutions, and neither in isotonic solutions.

Step2: Analyze Solution D

Solution D is a 6.97% (m/v) glucose solution. A 5.0% (m/v) glucose solution is isotonic. Since 6.97% > 5.0%, Solution D is hypertonic, causing crenation.

Step3: Analyze Solution E

Solution E is a combination of 5.0% (m/v) glucose and 0.9% (m/v) NaCl. Both 0.9% NaCl and 5.0% glucose are isotonic separately, but together they have a higher solute - concentration than blood (because we are adding solutes), so it is hypertonic and causes crenation.

Answer:

Solution D: crenation
Solution E: crenation
