Visualizing Concepts

The following diagrams represent aqueous solutions of two monoprotic acids, HA (A = X or Y). The water molecules have been omitted for clarity. (a) Which is the stronger acid, HX or HY? (b) Which is the stronger base, X- or Y-? (c) If you mix equal concentrations of HX and NaY, will the equilibrium

HX(aq) + Y-(aq) ⇌ HY(aq) + X-(aq)

lie mostly to the right (Kc > 1) or to the left (Kc<1)?[Section]
