Question 1
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 H
2O molecules are not shown.
Which outcome corresponds to the reaction:
HCN + OH
- → H
2O + CN
-?
◦ box (a)
◦ box (b)
◦ box (c)
◦ None of these
