A solution of sodium hydroxide is standard-
ized against potassium hydrogen phthalate
(KHP, formula weight 204.2 g/mol). From
the following data, calculate the molarity of
the NaOH solution: mass of KHP 1.654 g;
buret reading before titration 0.23 mL; buret
reading after titration 47.07 mL.
Answer in units of M

  • Chemistry -

    KHP + NaOH ==> NaKP + H2O
    So 1 mole KHP uses 1 mole NaOH.

    moles KHP = grams/molar mass. Calculate moles KHP
    Then moles NaOH = moles KHP
    M NaOH = moles NaOH/L NaOH.
    (mL NaOH used = final reading - initial reading, then convert to liters.)
