I'm being asked to find the pH of a 0.050 M solution of NaCN.(adsbygoogle = window.adsbygoogle || []).push({});

I figured out the expression to be x^2/ 0.050 -x, now all i need is a value for k, however I'm not given that value. I know the pH depends on the molarity of the hydrogen ion at equilibrium, however to find that I need to find x, and in order to find x I need a value for k. I would appreciate any help, thanks.
