Homework Statement


Determine acid concentration of a mixture of (COOH)2 and H2SO4 by titration against NaOH
Concentration of NaOH = 0.2M
Average Titre Figure (NaOH) = 8.93cm3
Volume of mixture added = 10mL

Homework Equations


2NaOH + (COOH)2 [tex]\rightarrow[/tex] 2NaCOO + 2H2O


The Attempt at a Solution


Reaction ratio NaOH: (COOH)2:H+ions = 2:1:2
Molarity of NaOH 0.2M
Moles of NaOH in 8.93mL = 1.786 x 10-3 mol
Moles of H+ ions = 1.786 x 10-3 mol in 10mL

A similar calculation for H2SO4. Then do you just add the moles and express in mols/L?
