Homework Help: Chemistry

Posted by Laura on Sunday, April 25, 2010 at 4:16pm.

Help needed on a homework problem -
solution of HCN and CN- , Ka 6.2x10^-10 . Is this a buffered solution? Shouldn't the pH be greater than 7, and [OH] >[H]?
Does adding a strong acid have more effect than adding a strong base?
Thanks.
