H3PO4 + 3KOH ==> K3PO4 + 3H2O
mols KOH = M x L = ?
Convert mols KOH to mols H3PO4.
M H3PO4 = mols H3PO4/L H3PO4
You titrate a 10.0 mL sample of phosphoric acid with a 1.65 M solution of the base potassium hydroxide. It takes 7.55 mL to reach the endpoint of the titration. What is the molar concentration of the original solution of phosphoric acid?
3KOH + H3PO4 --> K3PO4 + 3H2O
