Question

You titrate a sample of the acid containing 0.367 g of the acid using 0.3341 M NAOH solution. Your initial buret reading is 1.06 mL and your final buret reading is 25.83 mL. Determine possible molar mass values for the monoprotic and diprotic cases

MM HA: ___________

MM H2A: ___________

Since you has no real information about the unknown acid, you worry that you may not have chosen an appropriate indicator for the titration. Assume that you have a 10% uncertainty in the molar mass values. Calculate the possible range of molar mass values for each case

Explanation / Answer

You titrate a sample of the acid containing 0.367 g of the acid using 0.3341 M N
