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 1.744 g;
buret reading before titration 0.13 mL; buret
reading after titration 48.37 mL.
Answer in units of M

  • chemistry -

    KHP + KOH ==> H2O + K2P.
    mols KHP = grams/molar mass
    mols NaOH = mols KHP (see coefficients in the balanced equation.
    M NaOH = mols NaOH/L NaOH
