an experiment was carried out to investigate haemolysis of human blood cells.The red blood cells were placed in different concentrations of sodium chloride solution.The percentage of haemolysis cells was determined.The results were as shown in the table below salt concentration g/100cm3(%) 0.33 0.36 0.38 9.39 0.42 0.44 0.48 red blood cells haemolysis (%) 100 91 82 69 30 15 0 a) i)at what concentration of salt was the proportion of haemolysed cells equal to non haemolysed cells? ii)state the percentage of cell haemolysed at salt concentration of 0.45% b. i) account for the results obtained at (i) 0.33 percent salt concentration. ii) 0.48 percent salt concentration. c) what happened to the red blood cells if they were placed in 0.50 percent salt solution?
