Determine the pH at the equivalence point of a titration between 100.0 mL of [x] M HNO2 solution with [x] M KOH. Remember that only the decimals in a pH count as significant figures.  Please enter your answer with three decimal places. Ka for HNO2 = 7.1 x 10-4  

Select all species that are strong acids.

Determine the pH of a solution consisting of [x] M HNO2 and [y] M KNO2.  Remember that only the decimals in a pH count as significant figures.  Please enter your answer with three decimal places. Ka for HNO2 = 7.1 x 10-4

Select all species that are weak acids.

Determine the number of moles of NaCN that should be added to a 1.00 L solution of [x] M HCN to obtain a pH of [y].  Assume the addition of NaCN does not change the volume of solution. Ka for HCN = 4.9 x 10-10

Determine the concentration of C6H5NH2 that would produce a solution with a pH of [x]. Kb for C6H5NH2 = 4.0 x 10-10

The molar solubility of Ca(IO3)2 is found to be 3.8 x 10-3 M.  Determine the solubility product (Ksp) for this compound. Ksp = [coeff] x 10[exp]  

Match the type of information that can be gathered from an independent analysis on a fictional child: 

Determine the pH of a buffer consisting of [x] M HBrO and [y] M KBrO.  Remember that only the decimals in a pH count as significant figures.  Please enter your answer with three decimal places. Ka for HBrO = 2.3 x 10-9
