Calculate mw of unknown using titration

  • #1

Homework Statement



Calculate the molecular weight of unknown acid by titrating with 2N H2PO4 and 2N NaOH

Homework Equations



ph = pka + log[a-]/[ha]

The Attempt at a Solution



So i graphed titration with both acid and base with equivalents used vs ph, how would i use the number of equivalents (and total number of inflections in curve) to get molecular weight?

Not enough data. Please explain what the question is and what is the data that you are given. Or are you asked to design a procedure for determining molar mass of the acid?
