Consider the reaction A3+(aq) + B-(aq) ⇌ AB2+(aq) A) In 1.00 Liter of water at equilibrium, there are 1.00 moles of A3+, 4.00 moles of B- and 8.00 moles of AB2+ (aq). What is the value for the equilibrium constant? B) Draw an image to represent this initial state. (below) C) At some time, t, 13.00 moles of ABCl2 is added, the volume change is negligible. ABCl2 is a completely soluble compound that forms AB2+(aq) and 2 Cl-(aq) ions, the chloride ions are spectator ions and do not affect the equilibrium, you do not have to include them in the diagram. Draw two models to represent this occurrence; one for the instant the substance was added and once to show the reaction reestablishing the equilibrium.

One quick follow up...this works well with adding 13 moles. Do you use the same math if fewer or more moles were added? For exampl, what if 5 moles of AB2+ were added? Or 20 moles of AB 2+ were added?
