Answer #1

no of moles of KHP    = W/G.M.Wt

                                   = 0.503/204.22

                                     = 0.00246mole

    KHP(aq) + NaOH(aq)----------> KNaP(aq)   + H2O(l)

1 mole of KHP react with 1 mole of NaOH

0.00246moles of KHP react with 0.00246moles of NaOH

no of moles of NaOH   = molarity *volume in L

            0.00246         = molarity*0.0273

molarity   = 0.00246/0.0273   = 0.09M

molarity of NaOH   = 0.09M

a. 0.09M >>>answer

    3. A student pipetted 25.00 mL of a 0.2531 M solution of HCl into an Erlenmeyer flask. After adding 3 drops of phenolphthalein indicator to the flask, the student started adding NaOH from the burette, until the color in the Erlenmeyer flask turned light pink, The student calculated that 21.40 mL NaOH was transferred in the flask to neutralize the acid. a) Calculate the number of moles of HCl initially present (Reaction: NaOH(aq) + HCl(aq) -NaCl(aq) + H2O() b) Calculate...

    please help me speciqlly with 11. 12. 13. 14   Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...
