Question: is licn an acid or base?
Answer: Lithium cyanide, LiCN, is a salt formed from by the reaction of the weak acid hydrocyanic acid, HCN, and the strong base lithium hydroxide. The Ka of hydrocyanic acid is 4.90×10−10. Using this information, determine the pH of a 0.119 M solution of LiCN that is prepared at 25∘C.
