Two solutions are termed *isotonic* if they:
AAre equally polar
BHave the same osmotic pressure at a given temperature
CHave the same concentration in g/L
DBoil at the same temperature
Answer & Solution
Correct answer: B. Have the same osmotic pressure at a given temperature
**Isotonic = equal osmotic pressure**.
Separated by a semipermeable membrane, no net osmosis.
0.9% saline is isotonic with blood plasma — safe to inject IV.
