Both isotonic and isosmotic refer to the strength of the solution,  for example, how much solute is dissolved in the solution. Isotonic  refers to the ionic strength of a soâ¦lution while isosmotic refers  to the number of molecules of solutes in a biological solution, for  example, sugar concentration.
