Determine the number of moles of KClO that should be added to a 1.00 L solution of [x] M HClO to obtain a pH of [y].  Assume the addition of X does not change the volume of solution. Ka for HClO = 2.9 x 10-8

Select all TRUE statements concerning the graph shown.

Determine the molar solubility of Sr(IO3)2 in [x] M NaIO3.  It’s Ksp is 3.3 x 10-7. Our system can’t handle your tiny answer, so multiply it by 1,000,000 before entering.

Determine the pH at the equivalence point of a titration between 25.0 mL of [x] M C5H5N solution with [x] M HNO3. Remember that only the decimals in a pH count as significant figures.  Please enter your answer with three decimal places. Kb for C5H5N = 1.70 x 10-9
