question 22

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,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. Assume that an aqueous solution of hydroxide ion,OH<sup>-</sup>,represented by unshaded spheres,is allowed to mix with a solution of an acid,H<sub>n</sub>A,represented by gray spheres.Three possible outcomes are represented by boxes (a) -(c) ,where the black spheres represent A<sup>n</sup><sup>-</sup>,the anion of the acid.For clarity H<sub>2</sub>O molecules are not shown.   -Which outcome corresponds to the reaction: H<sub>2</sub>SO<sub>4</sub> + 2 OH<sup>-</sup> → 2 H<sub>2</sub>O + SO<sub>4</sub><sup>2-</sup>?
