write a balanced equation that describes an acid base reaction that would allow you to determine the moles of aspirin present in a sample

  • chemistry characterization & analysis of aspirin - , Tuesday, November 13, 2012 at 12:20am

    Aspirin is C9H8O4 and it has one acid H on it so I will rewrite it as HC9H7O4.
    HC9H7O4 + NaOH ==> NaC9H7O4 + H2O
    If you know the molarity of the NaOH and measure mL required for titration, then mol aspirin = M NaOH x L NaOH = mols NaOH = mols aspirin.

    You can see the structure and formula of aspirin here.
