Question

If a red blood cell (RBC) is placed in a 0.5% salt solution, which of the following would occur?

1. Water will move out of the RBC.
2. RBC will hemolyze.
3. RBC will crenate.
4. Water will enter the RBC.

Answer 1

1. Would make sense because salt attracts water. There would be salt diffused throughout the saltwater solution. So the water contained in RBC would seep out of cell wall towards the salt elements as water attracts salt. Wherever salt is, water follows.
