The flask shown here contains 0.649 g of acid and a few drops of phenolphthalein indicator dissolved in water. The buret contains 0.160 M NaOH. The volume of end point titration is 20.5ml. What is the molar mass of the acid (assuming it is diprotic and that the end point corresponds to the second equivalence point)?
After the addition of the water, the volume is now 480 mL. To this solution, we add 20.0 mL of 5 molar NaOH. What is the pH of the buffer now. What would be the pH after an addition of 60.0 ml of the 5.00 molar NaOH was added to the solution formed..
