A saturated lead(II) chloride solution has a chloride concentration of 3.24 x 10-2 mol/L. What is the Ksp? Put your answer in scientific notation and round to two decimal places. Ksp =

it is time for the titration.  You measure 15.0 mL of the H2C2O4 solution with a 100-mL graduated cylinder and add it to a 125-mL Erlenmeyer flask.  Then you add two drops of the indicator, phenolphthalein, to the oxalic acid solution in the flask.  You dispense the NaOH solution from the buret into the flask (while swirling the flask) until you reach the endpoint.  At the endpoint, the solution in the flask turns light pink.  You repeat the titration two additional times for a total of three trials.  H2C2O4 (aq) + 2 NaOH (aq) --> Na2C2O4 (aq) + 2 H2O (l)                                                (I)              (II)                (III) Volume of H2C2O4 used  15.00 mL   15.00 mL   15.00 mL Initial Buret Reading        0.00 mL    0.05 mL         0.10 mL Final Buret Reading           14.45 mL     14.38 mL    15.40 mL Volume NaOH used           ________mL          ________mL        ______mL Moles NaOH                     _______M      ________M    _________M…

What do you understand about the manufacture of chemical solutions? How to (a) make 1000 mL of 0.2 N hydrochloric acid solution from 1 N standard solution and (b) make 100 mL of 0.5 N sodium hydroxide secondary standard solution (known BM = 40 g / mL)? Explain!

5.00 ml of 7.35 M Fe(NO3)3 is combined with 1.00 mL of 0.50 M HCIO4 and 4.00 ml of 2.00 x 10-2 M KSCN. What is the concentration of Fe3+ in the solution after the other reactants are added? Enter your answer with two decimal places. Example: 1.32 Do not include units in your answer.
