Final+Lab+Report

Introduction
 * Our goal is to try and separate the dirt and oil from water with a 1- 100mL graduated cylinder, 1- 150 mL beaker ,1 glass funnel, 1 pinch clamp, 1 Styrofoam cup, filter paper, 1- 150ml Erlenmeyer flask, rubber tubing, sand, gravel, charcoal and fire from the island.
 * Our group of survivors came to the conclusion that our murky water is made of Oil,Dirt,and Water.
 * The first few experiments we formed and planned to do was to just straight out filter the water using filter paper, then we decided to put gravel and sand in a Styrofoam Cup and pour out water through that. When this didn't give us the outcome we expected we tried to use a pinch clamp method and tried to remove the oil from the water, and this failed as well. Then we decided to combine our second and third attempt. After, we figured that we should try and filter it. Then we mixed it with charcoal and then filtered it again. Last we boiled it to remove salt.

Procedure Trial 4
 * Pored sand and rocks into cup and poke a hole in the bottom of the cup
 * Poor 25ml of water into the cup
 * The water is going through the rocks and sand and going into the beaker
 * We added 25 ml more into the cup
 * All of the large particles in the water were removed, but the oil stayed in the water and oil and water entered the beaker.
 * Connected the funnel to the rubber tubing and placed the pinch clamp under the funnel
 * We then poured the water in it

Trial 5
 * Put filter paper in funnel
 * Pour water though and let filter

Trial 6
 * Mix about 5 milliliters of charcoal with the water
 * Run the charcoal/water mix through filter

Trial 7
 * Plug light bulb in and dip rods into water, if light turns on, salt is present
 * Put water in erlenmeyer flask and use a ring stand, ring clamp, and a Clay Triangle to suspend it over the bunsen burner.
 * Boil the water

Observations
 * During Trial 4, The water was coming out without oil until the rubber tubing got clogged with dirt.
 * After Trial 5 we concluded the water was cleared of particles but was left only with a greenish tint.
 * We realized in Trial 6 after mixing the charcoal and water it became black but after filtering it again it was clear and had no odor. We used two pieces of filter paper for removing the charcoal.
 * After Trial 7 we concluded that the water was clean and it was ready to drink.

Materials
 * For our procedure we used a flourence flask, rubber tubing, a funnel, a pinch clamp, filter paper, a styrofoam cup, sand, gravel, charcoal, and fire

Calculations
 * We measured the clean water we have. We have 36 milliliters of clean water which equalled 36% yield.
 * The steps using sand and gravel in the cup, and using the filter paper removed majority of the impurity seen by the average eye.

Discussion
 * For each step we wanted to remove at least a important impurity that prevented it from being drinkable. We realized that we couldn't remove oil until the large particles were gone and we couldn't remove the small particles until we removed the oil. Also, the smell and color couldn't be removed until we mixed it with charcoal and filtered it. At first we failed because we were doing the steps in the wrong order.
 * From our introduction we just switched the order and combined some of the steps. We are very satisfied from doing this because it lead us to drinkable water.
 * The impurities that we removed from our mixture were oil, dirt, salt, and small particles of some kind. Trial 4 removed oil and dirt, Trial 5 removed small particles, and Trial 7 removed the salt from out water.
 * The source of error in our procedures was a mixture of human error and a lack of configuration to the procedures. Our yield wasn't and shouldn't be 100% because in the process of purifying the water and having failed attempts we lose some of the water we started with.

Conclusion
 * In the ended we completely purified the water and was able to drink it. Our Group could have been a lot more efficient if we had worked faster but now that we know how to do it we are positive we would have work a lot faster if we were to do it again. Overall are group had a lot of team chemistry and we worked good together.
