Classification of Matter
Heterogeneous Mixturessee visibly different regionsgranitedirtcerealsoil & vinegarsee a boundaryice cubes in water
Homogeneous Mixturesparticles very small on atomic scaletoo small to be seen cant be sorted or trapped by filterwont scatter lightparticles evenly distributedmixture will not separate
Solutionhomogeneous mixture of 2 or more substances in a single physical state (phase)
Parts of a Solutionsolute = substance being dissolved
solvent = dispersing medium substance being dissolved in
Can you identify the solute and solvent in each picture?
hints to identify solute & solventsolute: substance that changes phase substance that have less of
solvent: substance that maintains phasesubstance that have more of
Aqueous Solutionswater is solventtransition metals form brightly colored solutions
Solutions occur in all 3 phases!
Gas in a liquid:CO2 in and out of water bubbles mean its a mixture not a solution!
