The following chemical equilibria are studied in this experiment. To become familiar with their behavior, indicate the direction, left or right, of the equilibrium shift when the accompanying stress is applied to the system. a. NH3(aq) is added to Ag+(aq) + Cl-(aq) -><-(double arrow) AgCl (s) b. HNO3(aq) is added to Ag2CO3(s) -><- Ag+(aq) + CO3 2-(aq) c. KI(aq) is added to Ag+(aq) + 2NH3(aq) -><- [Ag(NH3)2]+(aq) d. Na2S(aq) is added to AGI(s) -><- Ag+(aq) + I-(aq) e. KOH(aq) is added to CH3COOH(aq) + H2O(l) -><- H3O+(aq) + CH3CO2-(aq) f. HCl(aq) is added to 4 Cl-(aq) + Co(H2O)6 2+(aq)-><- CoCL4 2-(aq) + 6 H2O(l)
