Question

Assume we are to tackle a complex equilibria problem using the process we learned in class. In this example, we’re going to look at dissolving CuS in water.  The relevant equilibrium reactions are as follows:

CuS   ⇋   Cu2+   +   S2–                                                                                                                                  

Cu2+   +   OH–   ⇋   Cu(OH)2

S2–   +   H2O   ⇋   HS–   +   OH–                                                                                                         

 H2O   ⇋   H+   +   OH–

HS–   +   H2O   ⇋   H2S   +   OH–

Write 1 charge balance equation.
