Is sand a heterogeneous mixture?
September 05, 2010 4:21PM
Sand itself is homogeneous (each grain is homogeneous), however sand in general (lots of grains of sand, as in a handful of sand) is heterogeneous because it both has other things than sand mixed in and also it is not a pure solid (it is not a large rock of sand).
See the Related Questions to the left for more information about heterogeneous and homogeneous mixtures.
Sand itself is a homogeneous but it's not a mixture. It's a compound. If your talking about a bucket of sand it isn't uniformed throughout it would be a heterogeneous mixture because it's uniform of each piece of "sand" varies. It would be a homogeneous mixture if all the sand in the bucket where the uniformed throughout. For example if all the specs of sand in the bucket are SIO2 silicon dioxide it is a homogeneous mixture.
Chemistry the central science 11 editions and their book still confuses people. You think they could explain what they are talking about a little bit better. It's only a 400 dollar book.
