0.9% sodium chloride solution is good and balanced to RBC. A lab technician accidentally places a sample of RBC’s in 1.8% sodium chloride solution. What happens? Why?

When RBC placed in 1.8% NaCl solution solution become hypertonic i.e water move from lower concentration of solute to higher concentration of solute. Hence RBC shrinks.

0.9 % NaCl solution is good because it is isotonic to the cytoplasm of the red blood cells. Isotonic solutions are solutions that have similar concentrations.
1.8% of NaCl solution is an hypertonic solution to the cell cytoplasm of the red blood cells - that is, it is more concentrated, has more solutes. An hypertonic solution is a solution that has a higher concentration.
When red blood cells, or any other animal cells, are placed in a solution that is hypertonic, the cells lose water molecules from their cytoplasm to the solution due to the process of osmosis.
This will cause the red blood cells to shrink, a process known as crenation of the red blood cells.
