WebOct 18, 2016 · Tonicity is a behavioral term. It describes what a solution would do to a cell's volume at equilibrium if the cell was placed in the solution. A cell placed in a hypotonic solution will gain volume and swell. A cell placed in a hypertonic solution will lose volume and shrink. Tonicity cannot be measured on an osmometer, and it has no units. WebHypotonic dehydration, In contrast with hypertonic dehydration, refers to a decrease in electrolyte concentration in the extracellular fluid. In hypotonic dehydration, the cells grow as water in the extracellular fluid moves toward the higher sodium concentration inside the … WebTonicity is one of the factors that affects drug absorption.
