Homework Help: Question about Compound Notation

  1. Apr 12, 2009 #1
    I have a question about notation.
    What does it mean when you have two elements in parentheses seperated by a comma? For example,
    (Zn, Cd)S

    Also, what do elements which come after a colon mean? Specifically,
    (Zn, Cd)S: Cu, Al

    This should mean: sulfide of Zn and Cd (atoms of Zn and atoms of Cd in the same crystal of sulfide).
    Don't know this one; maybe it means: in a solution containing copper and aluminum ions.

    Is this maybe some sort of electrochem cell diagram format?
