Sugar Water: Homogeneous or Heterogeneous Mixture?

[travwg33]

Ok so starting chem in college and were going over the real basic stuff. Sugar water is classified as a homogeneous mixture, but once water exceeds it's dissolving capacity wouldn't the sugar water be a heterogenous mixture? Or both?

You will have two phases - one will be solution, other will be solid sugar. Both together will form heterogeneous mixture, solution by itself will be homogeneous mixture. This distinction in this case makes sense, as sugar will most likely settle at the bottom, so you will have a solution above. In other cases mixture can be in the form of a stable suspension, then there will be no homogeneous part.
