    How Does Hydrogen Sulfide Affect pH and Precipitation in a Cu-Zn Solution?

    Homework Statement A sol'n contains Cu+2(aq) and Zn+2 ions each at a con'c of 0.1M. Hydrogen sulphide gas is bubbled up into sol'n and dissociates having an initial con'c of 0.1M. Whats the pH of the final solution? Will any precipate form? I don't know how to start the problem. Pls help me...
