If the potato slice becomes soft and limp after soaking for one hour in the solution, the solution is hypertonic.
<h3>What is a hypertonic solution?</h3>
In biology, a hypertonic solution is a solution with more solute concentration than it is found in the sap of any other cell placed in it.
Such solutions have lower water potential than the cells placed in them. Thus, water will readily move by osmosis from the sap of the cells into the solution.
Cells that are placed in hypertonic solutions, therefore, usually end up becoming flaccid as a result of water loss.
So, if after soaking for one hour in a solution whose concentration is not known, a slice of potato becomes soft and limp, it means the solution is hypertonic.
