Trials

**Trial 1 - Experiment 1**

 * First hypothesis: If the water is boiled then the condensed and evaporated then water will be separated from the oil.
 * The first hypothesis could not be tested because oil cannot be near fire, there had to be another way to separate the oil and the water.
 * New hypothesis: If the contaminated water is filtered through filter paper and pushed down by gravel, then the water will be separated from the oil.

__Steps to Trial 1__
 * 1) Insert filter paper to fit at the neck of the Erlenmeyer flask.
 * 2) Pour the contaminated water into the flask.
 * 3) Take gravel and push down mixture into the flask.

__Observations:__
 * The new solution was more yellow with less contaminates inside.
 * However the new solution still had two layers, oil and water:



Trial 2 - Experiment 2
__Hypothesis__: If the water is poured into a funnel covered in filter paper, filled with sand and gravel, then the oil will separate from the water.

__Steps to Procedure:__
 * 1) Place a funnel inside an erlenmeyer flask
 * 2) Put a piece of filter paper inside and fill it with sand and gravel.
 * 3) Next Pour your toxic liquid mixture into the funnel.

__Observations:__
 * The water had separated from the oil.
 * Now the water is more clear with no bubbles.
 * Still smells like chemicals
 * Absolutely no chunky dirt left inside

Trial 3 - Experiment 3
__Hypothesis:__ If the liquid is poured into a funnel filled with charcoal the smell would go away, as well as the color.

__Procedure:__
 * 1) First put filter paper inside of a funnel.
 * 2) Second pour the liquid into a beaker.
 * 3) Third pour the charcoal in the beaker with the liquid.
 * 4) Next stir until it is completely black.
 * 5) Lastly pour the mix into the funnel.

__Data/Observation:__
 * Our liquid is completely clear like water.
 * The odor is gone.
 * looks like it still needs another step of purification.
 * No oil



**Trial 4 - Experiment 4**
__Hypothesis-__ If the water is boiled then the condensed and evaporated water will be salt free.

__Procedure:__
 * 1) First we measured our water.
 * 2) Second we put the Florence Flask containing our water on the ring stand which held it above the Bunsen burner.
 * 3) Third we put a glass stopper in the Flask and put a glass tube connecting the Flask to the Beaker where the water would be collected. (The glass tube is hallowed and around it is cold water to cool the water vapors.)
 * 4) Fourth the cooled water began to fill up in the Beaker and the salt remained in the Florence Flask.

__Data/Observation:__
 * Our water is completely clear.
 * It has no odor.
 * There is no oil in it.
 * It does not contain any salt.
