The following mixture of hydrocarbons is obtained as one stream in a petroleum refinery. Q : What are isotonic and hypotonic The two solutions which are having equivalent osmotic pressure are called isotonic solutions. The isotonic solutions at the same temperature also have same molar concentration. If we have solutions having different osmotic pressures then the solution having different
