DIVERSITY OF MATTER
MIXTURES
HETEROGENOUS MIXTURES
YOU CAN SEE ALL OF THE COMPONENTS BY LOOKING AT IT
HOMOGENEOUS MIXTURES
YOU CAN'T SEE ALL OF ITS COMPONETS BY LOOKING AT THEM
HOMOGENEOUS MIXTURES ARE CALLED SOLUTIONS
SOLVENT: IS THE COMPONENT THAT IS IN A GREATER PROPORTION MIXTURE (EX. WATER IS THE SOLVENT OF THE SEA WATER)
SOLUTE: IS THE COMPONENT OF THE SMALLER PROPORTION. SOMETIMES A SOLUTION HAVE MORE THAN ONE SOLUTE (EX. SALT IS THE SOLUTE OF SEAWATER)
SOLUTIONS
COLLOIDAL DISPERSIONS
COLLOIDS: ARE HETEROGENEOUS MIXTURES THAT HAVE A HOMOGENOUS APPEARANCE
EMULSION IS A COLLOID FORMED BY TWO IMMISCIBLE LIQUIDS
WHEN TWO SUBSTANCES ARE
IMMISCIBLE
AND EVEN IF WE MIX THEM,TOGETHER IN A BLENDER. THEY WILL SEPARATE IN THE END. SO WE NEED TO ADD A THERD SUBSTANCE CALLED AN
EMULSIFIER
, WHICH HELPS HOLD THE MIXTURE TOGETHER
MIXTURES: ARE SISTEMS THAT CONSISTS OF TWO OR MORE SUBSTANCES
MATER ALL AROUND US
HOMOGENOUS SISTEMS
ARE SYSTEMS THAT APPEAR UNIFORM THROUGHT OUT
HETEROGENOUS SISTEMS
SOME PARTS OF THESE SYSTEMS OF MATTER LOOK DIFFERENT
SUBTANCES
CHEMICAL COMPUNDS (IS NOT A MIXTURE)
COMPOUND: IS A SUBSTANCE FORMED BY TWO OR MORE COMPONETS MIXED IN FIXED PROPORTIONS
MIXTURE: CONSISTS OF TWO OR MORE SUBSTANCES (SIMPLE OR COMPOUND) THAT MAY BE COMBINED ANY PROPORTION
PURE SUBSTANCES: CANNOT BE SEPARATED FROM OTHER SUBSTANCES USING PHYSICAL PRODUCERS
SIMPLE SUBSTANCES: MADE UP OF A SINGLE CHEMICAL ELEMENT (HYDROGEN)
SEPARATING THE COMPONENTS OF A MIXTURE
THE COMPONENTS IN A MIXTURE HAVE DIFFERNT PROPERTIES AND WE CAN TAKE ADVANTAGE OF THIS TO SEPARATE THEMFROM THE MIXTURE
TO SEPARATE THE COMPONENTS OF A MIXTURE WITHOUT CHANGING THE SUBSTANCES , WE USE A PHYSICAL METHODS
PROCEDURES FOR SEPARATING HOMOGENEOUS MIXTURES
EVAPORATION AND CRYSTALLISATION:EVAPORATION CAN BE SPEEDED UP BY HEATING THE LIQUID
DISTALLATION: TWO MISCIBLE LIQUIDS THAT HAVE DIFFERENT BOILING TEMPERATURES
EXTRACTION USING SOLVENTS: THIS TECHNIQUE IS USED FOR SEPARATING ONE OF THE COMPONETS IN A MIXTURE, USING A SOLVENT THAT DISSOLVES ONLY ONE OF THE COMPONENTS
SIEVE: SEPARATE SOLID MIXTURES WITH COMPONTENTS THAT HAVE DIFFERNT-SIZED PARTICLES
DECATANTION: SEPARATE TWO IMMISCIBLE LIQUIDS. TO SEPARATE THEM WE USE A SPECIAL FUNNEL CALLED A SEPARATING FUNNEL
MAGNETIC SEPARATION: IF MIXTURES CONTAINS FERROMAGNETICS METALS. EASILY USING MAGNETIC SEPARETION
FILTRATION: SOLID FROM LIQUIDS. THE PARTICLES OF THE SOLID ARE BIGGER THAN THOSE LIQUIDS
