Consider a 0.80M solution of HCN. The Ka of HCN is 6.2x10-10. What are the major species in solution? Calculate the pH of this solution.


Ok, so i took a break, came back, and finished the problem. I have an x value of 2.23x10-5. I took the negative log of that and came up with a pH of 4.65, Is this close to what it should be, or did i miss something?

    You didn't miss anything. That's the correct answer.
