pure substance is the same thorough out doesn't vary
mixture a blend of two or more kinds of matter
heterogeneous are not uniform through out/you can see its mixture
homogeneous are uniform in composition/ you cant see that its a mixture
solutions homogeneous mixtures
solvent the dissolving medium/ it stays
solute the substance being dissolved/ it leaves
alloys solid solutions/ two or more metals are uniformly mixed/ ex: brass /advantages: higher strength and greater resistance to corrosion
suspensions mixtures in which particles of the mixture are more or less evenly dispersed throughout a liquid or gas
colloids particles that are intermediate in size between those in solution and suspensions.
the Tyndall effect particles that are large enough to scatter light
Brownian motion at a right angle this motion is due to collisions rapidly moving molecules / discovered by Robert brown
factors affecting solubility (the ability of a substance to be dissolved) temperature pressure surface area agitation
polar ionic compounds dissolves in water because water is polar
nonpolar compounds dissolve non-polar substances
acids substances that in solution can donate a hydrogen ion (proton) to another substance
bases substances that in solution can accept a hydrogen ion from another substance
