Introduction to Filtration
What do characteristic properties have to do with filtration? Filtration separates substances by using the characteristic property of solubility Filtration is the action or process of filtering something.
Experiment 5. 5 We filtrated 2 substances using a filter Sulfur is insoluble in water Salt has a solubility of 0. 4 g/m. L
What substance was stopped by the filter? Sulfur is yellow The filter paper was yellow There was no yellow in the filtrate
Filtrate The filtrate is the clear liquid that is left over after the solution is poured through the filter paper. Label in the next picture Filtrate Filter paper Funnel

Salt & Sugar The solubility of salt is 0. 4 g/m. L in water The solubility of sugar is 2 g/m. L in water Could we completely separate salt from sugar using water as a solvent?
Salt & Sugar cont. Salt is insoluble in alcohol Sugar is soluble in alcohol What will happen if we use alcohol instead of water?
Salt and Sugar Demo What happens to the salt? What happens to the sugar? What would happened if yesterday’s experiment was performed with salt, sugar & alcohol?
Experiment 5. 8: Chromatography is a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction
Chromatography Applications Environmental engineering Forensics
Chromatography Demo After this demo, you will have to write the procedure for our own chromatography lab that we will perform tomorrow.
Pre-lab Purpose: To investigate if ink is a mixture, and separate the substances in ink if it is. Hypothesis: Do you think is a mixture? How many substances do you think are in ink? Explain Procedure: Write with help from the book and demonstration Data Table: What will be measured in this experiment? Substance Distance Travelled
