QUESTION 2 Consider the following equilibrium: CO32- (aq) + H20 (I) HCO3 (aq) + OH" (aq) What is the effect of adding CaCl2 (aq) to this equilibrium mixture? a. The OH ions are neutralized, causing a shift to the right (towards products). O b.- he precipitate CaCO3 (s) is formed causing a shift to the right (towards products). OC There is no effect when adding CaCl2 (aq). d. O d. The precipitate CaCO3 (s) is formed causing a shift to the left (towards reactants). Oe. The OH ions are neutralized, causing a shift to the left (towards reactants).

Step 1
Le Chatelier's principle:
This principle is used to predict the effect of a change in conditions on chemical equilibrium. This principle states that when any system is at equilibrium and if we change in concentration, temperature, or pressure the system changes to a new equilibrium to cancel the change.
