a
A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.

Does this molecule contain a glycosidic bond?
If you said this molecule does contain a glycosidic bond, write the symbol
describing it.
If you said this molecule does contain a glycosidic bond, write the common
names (including anomer and enantiomer labels) of the molecules that
would be released if that bond were hydrolyzed.
If there's more than one molecule, separate each name with a comma.
