Osmolarity Flashcards
A solution containing 220mM of permeable solutes and 220mM of non-permeable solutes would be…
Hypotonic and Hyperosmotic
A solution containing 100mM of permeable solutes and 100mM of non-permeable solutes would be…
Hypotonic and Hypo-osmotic
A solution containing only 300mM of permeable solutes would be…
Hypotonic and Iso-osmotic
Initially, a cell is floating in a 1-L flask full of extracellular fluid, and it is in osmotic equillibrium at 300mOsm. If you added a MEMBRANE-PENETRATING solute to the solution in the flask, what would happen to (a) the osmolarity of the extracellular fluid, (b) the osmolarity of the intracellular fluid, and (c) the volume of the intracellular fluid once a new equilibrium is reached compared to before the new solute was added?
(a) The extracellular osmolarity would increase
(b) The intracellular osmolarity would increase
(c) The The volume of the intracellular fluid would stay the same
A solution containing 50mM of permeable solutes and 300mM of non-permeable solutes would be…

A solution containing 400mM of permeable solutes and 200mM of non-permeable solutes would be…
Hypotonic and Hyperosmotic

Hypotonic and Hyperosmotic
Initially, a cell is floating in a 1-L flask full of extracellular fluid, and it is in osmotic equillibrium at 300mOsm. If you added a NON-MEMBRANE-PENETRATING solute to the solution in the flask, what would happen to (a) the osmolarity of the extracellular fluid, (b) the osmolarity of the intracellular fluid, and (c) the volume of the intracellular fluid once a new equilibrium is reached compared to before the new solute was added?
(a) Extracellular osmolarity would increase
(b) Intracellular osmolarity would increase
(c) Intracellular volume would decrease
