If the mass of acetic acid taken for titration is 29.28 g, and the net volume of NaOH is 11.98 mL(initial: 5.5 mL, final: 17.49), what are the millimoles of NaOH to endpoint of titration?
Balance the following oxidation-reduction reactions that occur in basic solution.
an aqueous solution that contains 285ppm of potassium nitrate kno3 is being used to feed plants in a garden. what
Come up with a practical use for Prep-GC coupled with IR spectroscopy. Hint: if you can't identify your compound and you have a large peak above 3000 cm^-1, then think of a very common liquid that has OH's.
The mass of a beaker is 5.333 g. After 5.00 mL of a concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and the hydrochloric acid sample is 11.229 g. From the data, what is the measured density of t..

Describe how you could make 1L of a 0.1M potassium phosphate buffer at pH=7. The reagents available to you are solid KH2PO4 (m.w. 136.1g/mol) and K2HPO4 (m.w.174.2 g/mol). The pKa for the second ionization of phosphoric acid is 6.86.
The Ksp for calcium sulfate is 7.1 x 10^-5. What is the concentration of Ca^2+ in equilibrium with CaSO4(s) if [SO4^2-] = 2.0 x 10^-2 M
Most of the solid did not dissolve because the Ksp of ferric hydroxide is very small at 3 x 10^-39. However, when a certain amount of strong acid was added, the entire amount of solid dissolved. Determine the pH of the solution at that point that ..
