    Solution = homogeneous mixture Mixture at least two substances Substance = an element or a compound How can we distinguish a mixture from a compound? Homogeneous  uniform properties throughout the sample; components are  evenly dispersed throughout the sample; dispersed particles  too small to be seen even if you shine light on the mixture If dispersed particles large enough to be seen by unaided eye  (and settle on standing): suspension  If dispersed particles to small for unaided eye and do not  settle on standing, but can be seen by shining light on the  mixture (Tyndall effect): colloidal dispersion
