Title: Calculate molarity of 100 ml of diluted ASA?
Post by: Whapper2006 on November 18, 2008, 09:19:20 PM

You add .50 grams of Acetylsalicylic acid (ASA) (180.157g/mol) in a 125ml flask. then you add 10 ml of 1.0M sodium hydroxide and 10 ml distilled water. then heat to hydrolyze ASA, cool, and then ad 20ml of .10M nitric acid. pipet 10ml of this solution and transfer to a 100mL flask. what is the molarity of the diluted ASA? please help i dont understand how to do this

Step 1:

Can you write a balanced equation for the hydrolysis of acetylsalicylic acid?
