Summary:I describe two candidate representations of a mixture. The first, which I call the standard representation , is not a good representation of a mixture in spite of its widespread popularity. The second, which I call Gibbs's representation , is less widely adopted but is, I argue, a much better representation. I show that once we have a precise mathematical structure that can be used to represent thermodynamic systems, and once an adequate perspective on representation is adopted, Gibbs's representation trumps the standard representation.
