Question

what is meant by following solution types : hypotonic , isotonic and hypertonic

Answer 1

hypertonic means greater concentration of standard soln
isotonic means same concentration of standard soln
hypotonic means lower concentration of standard soln

Answer 2

A hypotonic solution is a solution that has a lower solute concentration compared to another solution. ... Hypotonic is a description of the solute content of one solution in relation to another solution. 

(2) isotonic
an isotonic solution is that solution which has same osmolarity or solute concentration as like another solution

(3) hypertonic

a hypertonic solution contain a higher concentration of solutes as compared to another solution
