Each symbol in the box below represents a mole of a component in one liter of a buffer solution; represents the anion the weak acid Water molecules and the few H⁺ and OH^– ions from the dissociation of HX and X^– are not shown. The box contains 10 mol of a weak acid, in a liter of solution. Show what happens upon

(a) the addition of 2 mol of

(b) the addition of 5 mol of

(c) the addition of 10 mol of

(d) the addition of 12 mol of

Which addition (a)–(d) represents neutralization halfway to the equivalence point?
