Standardization of 0.1 N HCl:
----------------------------
Weigh accurately 0.5 g of tromethamine which is previously
dried at 105° C for 3 hours add 50 mL of water and add 2
drops of bromocresol green indicator and titrate against
0.1 N HCl to pale yellow end point.(As per USP)
Formula = wt of tromethamine (mg)
________________________
121.14 X mL of HCL

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
