Homework Help: Chemistry

Posted by Question on Sunday, February 11, 2007 at 5:38pm.

What is the molarity of a phosphoric acid solution if 32.3 mL of the phosphoric acid solution is titrated to the final equivalence point with 20.6 mL of 0.581 M sodium hydroxide acid solution?

H3PO4 + 3NaOH ==> Na3PO4 + 3H2O

mols NaOH = 0.0206L*0.581 M= ??
mols H3PO4 = 1/3*?? = xx.
M=mols/L = xx/0.0323 = answer.
Check my thinking. Check my work.

Post you work if you get stuck.
