Does 1,3-cyclohexanediol contain any stereocenters? If so, mark them then determine how many different stereoisomers exist. Draw Fischer projections for all unique stereoisomers and identify the sets of enantiomers and diastereomers.
Determine the [OH-] of a solution that is 0.230 M in HCO3-. Also determine the pH of this solution.
