It requires 37.0 mL of a sodium hydroxide soltution to neutralize 0.75 grams of phosphoric acid. Using a balanced equation, determine the concentration of the sodium hydroxide solution.

  • Chemistry - ,

    3NaOH + H3PO4 ==> Na3PO4 + 3H2O

    mols H3PO4 = grams/molar mass.
    mols NaOH = 3x mols H3PO4 (from the equation).
    M NaOH = mols NaOH/L NaOH.
