Final answer:
The correct answer is that the solution is isotonic, where the solute concentration equalizes the osmotic pressure with the electrical effect, resulting in no net water movement across the cell membrane.
Step-by-step explanation:
A solution that has a concentration effect on diffusion that is equal, but opposite, to the electrical effect is described as isosmotic. However, this term wasn't provided as an option in the question. Since the question is looking for a term amongst isotonic, hypotonic, and hypertonic, the correct answer is isotonic. An isotonic solution has a solute concentration equal to that of another solution, resulting in no net movement of water across a semipermeable membrane due to osmotic pressure.
In comparison, a hypertonic solution has a higher solute concentration than another solution, which leads to water leaving a cell if placed in such a solution, potentially causing the cell to shrink. Conversely, a hypotonic solution has a lower solute concentration, and placing a cell in a hypotonic solution would result in water entering the cell, which may cause it to swell.
It is important to match the osmotic pressure of intravenous solutions with that of body fluids to prevent damage to cells. This highlights the importance of understanding the concepts of isotonic, hypertonic, and hypotonic solutions in medical and biological applications.
