Is water hypertonic hypotonic or isotonic?
Blood is isotonic. Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Tapwater and pure water are hypotonic. A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
That IV is full of saline, a liquid with the same concentration of solutes as your blood cells. Because you want your blood cells to sit in an isotonic solution. An isotonic solution is when two solutions, separated by a semipermeable membrane, have equal concentrations of solutes and water.
- LR is isotonic. It is very similar to plasma. And btw, while D5W goes in isotonic, the dextrose is quickly metabolized and the net result is electrolyte-free water, which is hypotonic, so we learned that D5W is hypotonic, not isotonic. Figure that one out yourself, but LR is definitely isotonic.
- Its osmolarity is generally around 308, but it is still considered isotonic because it contains the electrolyte combination NaCl as its solute. D5W, a dextrose based solution, is also actually considered isotonic (while in the bag). However, it is considered hypotonic while in the body (260).
- Hypertonic saline refers to any saline solution with a concentration of sodium chloride (NaCl) higher than physiologic (0.9%). Commonly used preparations include 2%, 3%, 5%, 7%, and 23% NaCl. HTS may have an important role in preventing and treating the effects of secondary brain injury.
When a cell is immersed into a hypertonic solution, the tendency is for water to flow out of the cell in order to balance the concentration of the solutes. Likewise, the cytosol of the cell is conversely categorized as hypotonic, opposite of the outer solution. Hypotonic refers to a lesser concentration.

- An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side. AP Chemistry: Help and Review / Science Courses.
- IV fluid tonicity
0.9% NaCl (normal saline) isotonic 0.45% NaCl hypotonic 2.5% dextrose hypotonic Lactated Ringer's solution isotonic D5W (acts as a hypotonic solution in body) isotonic
IV fluid tonicity
|0.9% NaCl (normal saline)||isotonic|
|Lactated Ringer's solution||isotonic|
|D5W (acts as a hypotonic solution in body)||isotonic|
- The following is a list of solutions by their tonicity:
- Hypertonic: D5 NaCl. D5 in Lactated ringers. D5 0.45% NaCl.
- Isotonic: 0.9% NaCl (Normal Saline) Lactated Ringers. D5W (In the bag)
- Hypotonic: D5W (in the body) 0.25% NaCl. 0.45% NaCl (half normal saline) 2.5% Dextrose.
- Types of IV Fluids. There are different types of intravenous fluids used to treat dehydration. Normal saline contains sodium and chlorine, so it replaces lost fluid and prevents or corrects some types of electrolyte imbalances. A solution of dextrose and water may also be used to treat dehydration.
- D5W is technically isotonic, but it becomes hypotonic once in the body so it pulls fluid out of the vasculature and into the cells. This is because once D5W is in the body, the dextrose is metabolized and you are left with free water, which is hypotonic.
