Melting #4: Testing the Liquid

Melting #4: Testing the Liquid

In the last time: I extracted water from Copper (II) Sulfate, and I would like to test it. What I would like to know is: can we drink it. Let’s find out.

The liquid

I didn’t use a rubber stopper to close the test tube because the new test tubes didn’t fit it. At least, I can close it with a tissue.

 

The first thing that I always do when I test liquids is to check the PH.

A better tool for this task is a PH meter, but I don’t have one. So I have to use the old-fashioned litmus paper.

The left piece of paper is the liquid that we’re testing now and the right is drinking water from bottles (not tap water). And on the top is a chart of what the litmus paper is indicating. Looks like the liquid is acidic and the drinking water is about in the middle.

It smelled like plastic when I smelled the liquid, I’m guessing it’s because the rubber tube that I used is heated and the plastic smell comes out.

After that, I thought about PH indicators. I used Phenolphthalein, Bromothymol blue, and Methyl orange. Phenolphthalein is colorless from 0 PH to 8.3 PH, Bromothymol blue will be yellow from 1 to 6 PH, and Methyl orange is red from 1 to 3.1 PH.

Well, I guess you can’t drink it. I thought that I could manufacture water from it.

Thought it will work but I guess the only place you could obtain water is from nature 🙂

  1. I’m glad you did not drink it!
    I think you can get water from experiments like this, but I guess it would have to be distilled and purified before you could pass it for drinking. 🙂

  2. I agree! Nature is my choice after seeing your experiment!!!!
