Two solutions are said to be **isotonic** if they:

Question

Accepted Answer

C. Exert the same osmotic pressure at the same temperature

Isotonic solutions are those that exert equal osmotic pressure at a given temperature
this implies equal molar concentration (and hence equal $iC$ if dissociation differs).
Hypertonic and hypotonic refer to higher and lower osmotic pressure relative to a reference, respectively.
