VermiglioKralHehirCassa Introduction: We believe that there is oil and dirt in the water. We are going to separate the water from the oil by running it through the filter paper and then we are going to add charcoal ash to the water. Then filter it.
 * Trial 4

Procedure/observations: The water was drained out through the filter paper and into the flask. The dirt was caught in the paper and in the funnel.

Calculations: || procedure || approx time || initial volume || observations before procedure || final volume || observations after procedure ||
 * filter paper || 5 min 42 sec ||  || the water was going to pour down the funnel into the beaker ||   || the water came out into the flask and the dirt stayed up in the filter paper ||

Discussion: We questioned if it would work if we used filter paper to get the dirt out of the water. it still looked a little dirty. So we decided to use charcoal and it worked. It captured the dirt and it poured out the clean water.

Conclusion: At the end of the experiment, the water was mixed in with charcoal and then was put into filter paper. Then as the water went through it turned into clear water.

Tyler, Joey, Brendan, Dan Trial 4 Lab Report

Hypotheses- To use the charcoal to absorb substances like odor, sulfur and other things from the water.

Introduction- We placed the charcoal in the filter paper. We then poured the water into the filter paper with the charcoal. The charcoal will most likely absorb the sulfur, odor, left over sand and dirt inside the water.

We got 27ml of water after we sent it through the charcoal. We tested the water with the light bulb and found out that it has salt in it.

Procedure- Place filter paper in funnel Put charcoal in the filter paper Put the water in the filter paper so the charcoal will absorb substances The water will come out the bottom clear

Equipment- Funnel, filter paper, charcoal, water, and the flask

Conclusion- The charcoal successfully absorbed all those substances making our water nice and clear.

Trial 5: kalb

Hypothesis: After we completed step 4 we take the water and run it through the filter paper, this removes the small particles from it.


 * 1) Complete Trial 4
 * 2) Put filter paper in funnel
 * 3) Pour water though and let filter

Conclusion: The water was cleared of particles but was left only with a greenish tint

Trial 6: pic with charcoal mixed in

Hypothesis: We take water from Trial 5 and mix with charcoal. Then run the charcoal/water mix through filter paper. The purpose of the charcoal removes the odor from the water as well as removes the coloration.


 * 1) Complete Trial 5
 * 2) Mix about 5 milliliters of charcoal with the water
 * 3) Run the charcoal/water mix through filter

Conclusion: The charcoal did remove the coloration and odor from the water.

kalb

__Notes After Trial 6:__ We measured the clean water we have. We have 36 milliliters of clean water which equalled 36% yield.

Trial 7:kalb pic of boiled water

Hypothesis: After we test the water for ions (salt) We are going to boil our water to remove salt and kill any bacteria present, we will use a Erlenmeyer Flask to boil it because the neck is smaller and we wont lose as much water.


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

 * TRIAL 4**

we didnt do anything today because we didnt have enough time to get anything finished we have set up what we have to do for the last day these are the pictures of the last thing we did which was to make the water clear.





**Trial 4**
2. Procedure/Data/Observations We used the bottle of water and oil, a ringstand, a clamp, a flask, and an iron ring. Then we put a tube at the end of the funnel, into the flask. We put the clamp on the tubing. Next we poured our liquid into the funnel, and waited a few minutes for the oil and water to be at the bottom completely. We let the water go through but put the clamp back on to stop the oil from coming through. Our volume was 25 mL after our purification. We are keeping the water and moving the oils
