- Match the following descriptions to the tonicity adjusting method which they describe. - Cryoscopic method - White-Vincent Method - E method - Sprowl's method It is the most widely used method in adjusting tonicity by the amount of sodium chloride. This method expresses the freezing point in terms of 1% solution. This method uses a constant that denotes the volume of isotonic preparation in milliliters when 1 gram of sodium chloride is dissolved in water. This method uses a constant of 0.3 to denote the weight of the drug. This method uses the equation "V = 33.33E".Using DEAE-cellulose as ion exhange resin, indicate the starting and ending pH for the narrowest experimental pH range used to seperate an amino acid mixture consisting of Gln, Leu and Lys Starting pH: Ending pH:2nd Question: For the above conditions, what is the corresponding dosage of chlorine andmonochloramine to achieve the desired degree of disinfection. same effluent concentration (2 mg/L) for both free chlorine and monochloramine
