HELP 100 POINTS explain how you would separate the components of a dirty water mixture that consists of: • coffee grounds • garlic powder • vegetable oil • sodium chloride (table salt) • gravel and sand • water. For each step discuss what separation method you are using and why you chose that method

Note that all detail explanation on why or how will be attached at the end

Step 1: Removing the Oil

Theoretically, step 1 and 2 can be alternated and preferably I would start with step 2, but I thought of one first. I would begin by setting up the liquid mixture in a funnel with a closed twist valve. Once the water mixture and oil has separated, I would slowly remove all the water, leaving the oil.

Step 2: Removing the Gravel and Sand

The second step is to filter out solids by using a sand filter. This filter is made by using a Styrofoam cup that has had small holes punched into the bottom with an open paperclip. The cup is filled with layers of clean washed gravel. The gravel will be layered by putting course gravel in the bottom and fine sand in the middle followed by course sand on the top. The gravel on the bottom stops the loss of sand out of the holes and the gravel on top stops the sand from washing out as a sample is poured.

Step 3: Removing the Coffee Grounds and Garlic Powder

You would start by lining a clean funnel with a coffee filter or something comparable. Then, you would add a spoonful or so of Charcoal to the funnel. Then you would pour the mixture of water, garlic powder, salt and coffee grounds into it.

Step 4: Removing Salt

You would preform a simple evaporation to remove the salt from the water. If the water is still needed, then you can preform a sealed distillation which has the same effect, but just keeps the water.

Step 5: Celebrate!

If you are doing this is a school, congratulations! you just finished your assignment/lab! If you are doing this in the wilderness for survival, congratulations! you won't die so soon!*

*The purification of water will not guarantee your extended survival in the wilderness, just extend the time in which you will not die of dehydration.™

Explanation:

Step 1 works because the density of oil and water are different, so as you let the liquid settle, the two liquids will separate into two sections. This allows you to funnel the water out. Step 2 work because the gravel and sand you want out cannot pass the sand-gravel filter you made (as long as it was made correctly) Step 3 works because the garlic powder and coffee grounds cannot pass the filter and the smell and colour that leaked into the water would be removed by the charcoal. Step 4 works because as water evaporates or is boiled off, the salt cannot evaporate with it, so it is left behind. Like how I was in the mall. Step 5 works because this was a long explanation and now you can go look at memes.

the answer is minerals.
