Assume That an Aqueous Solution of Hydroxide Ion,OH^-,represented by Unshaded

Multiple Choice

Assume that an aqueous solution of hydroxide ion,OH^-,represented by unshaded spheres,is allowed to mix with a solution of an acid,H_nA,represented by gray spheres.Three possible outcomes are represented by boxes (a) -(c) ,where the black spheres represent A^n-,the anion of the acid.For clarity H₂O molecules are not shown.
-Which outcome corresponds to the reaction: HCN + OH^- → H₂O + CN^-?

A) box (a)
B) box (b)
C) box (c)
D) None of these
