A 35.00 mL sample of an unknown H3PO4 solution is titrated with a 0.120 M NaOH solution. The equivalence point is reached when 24.48 mL of NaOH solution is added.The neutralization reaction is:H3PO4(aq) 3NaOH(aq) → 3H2O(l) Na3PO4(aq)When I tried it, I got 0.02, but that is not correct. So if you could explain it to me, it would be appreciated. Thanks.What is the concentration of the unknown H3PO4 solution?
