Consider the exothermic reaction CoCl42-(aq) + 6 H2O(l) Co(H2O)62+(aq) + 4 Cl -(aq). Will the equilibrium concentration of CoCl42- increase or decrease when the following changes occur?
a) HCl is added.
(b) Co(NO3)2 is added.
both of those compounds are not even in the equation?? how am i suppose to know?
