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, HnA, represented by gray spheres. Three possible outcomes are represented by boxes (a)-(c), where the black spheres represent An-, the anion of the acid. For clarity H2O molecules are not shown.




Which outcome corresponds to the reaction:
HCN + OH- → H2O + CN-?
◦ box (a)
◦ box (b)
◦ box (c)
◦ None of these

Question 2

Assume that an aqueous solution of hydroxide ion, OH-, represented by unshaded spheres, is allowed to mix with a solution of an acid, HnA, represented by gray spheres. Three possible outcomes are represented by boxes (a)-(c), where the black spheres represent An-, the anion of the acid. For clarity H2O molecules are not shown.




Which outcome corresponds to the reaction:
H2SO4 + 2 OH- → 2 H2O + SO42-?
◦ box (a)
◦ box (b)
◦ box (c)
◦ None of these
