One property of this solution is that it be isotonic with human blood. a. Isotonic solutions have definitions that it has the same osmotic pressure as 0.92% w/v aqueous solution of NaCl and has a freezing point of -0.52 °C. Show that these two definitions are in reasonably close agreement given that we are using solution concentrations rather than activities b.
