1.2 Classification of Matter-Part Deux Ch. 1: Matter and Change 1.2 Classification of Matter-Part Deux

Pure Substances every sample has same: are made of: characteristic properties composition are made of: one type of atom: element Ex: iron, gold, oxygen 2 or more types of atoms: compound Ex: salt, sugar, water

Chemical Purity chemicals in lab are treated as pure all chemicals have some level of impurity different grades of chemical are used for different purposes

Which are pure substances?

Mixtures blend of 2 or more types of matter each component keeps its own identity and properties the components are only physically mixed can be separated using physical means properties of the mixture are a combination of the properties of the componenent’s properties

Homogeneous Mixtures also called solutions uniform in composition no visibly distinguishible parts Ex: vinegar clean air salt water brass

Heterogeneous Mixtures not uniform in composition visible parts Ex: soil concrete blood chocolate chip cookies sand in water iced tea with ice

Mixtures

Physical Separation Techniques Filtration- solid part is trapped by filter paper and the liquid part runs through the paper Vaporization- where the liquid portion is evaporated off to leave solid

Physical Separation Techniques Decanting- when liquid is poured off after solid has settled to bottom Centrifuge- machine that spins a sample very quickly so that components with different densities will separate

Physical Separation Techniques Chromatography- used to separate mixtures because different parts move quicker than others.
