Best ResponseYou've already chosen the best response.0PH=4.47+, 397 =5.137 Where 4.47 is the ve log Ka =pka And , 397 is log base/acid This is Handerson equation by which you can detrmine the ph of buffer solution

Best ResponseYou've already chosen the best response.0PH=Pka + log [base]/[acid] It is used only for buffer solution. Your compounds are salt of conjugate base which is NaOCN And acid which is HOAC And this is buffer solution.

Best ResponseYou've already chosen the best response.0I think it is true , but if you have noticed something wrong , I'll be glade to learn it from you

Best ResponseYou've already chosen the best response.0I mean the numerical values must be calculated again. pKa is not 4.47 and log [base]/[acid] is not +0.397
