An aspirin weighing .4g was mixed with 2mL of 1M sodium hydroxide solution and 10mL water and brought to boil. The solution was then diluted to 100mL with water. 1.00mL of the dilute solution was placed in a 50ml flask and filled to the 50mL level with a .039M iron (lll) chloride stock solution.
How do find out the percent age of ASA in the aspirin tablet?
