Let me begin by introducing myself,
Well, I will refer to myself as Burbuat. I have, for the past 4 days, tried to identify an unknown substance provided for me by my teacher. We have 8 days to identify this unknown substance, but I am afraid I will not be able to correctly identify this unknown substance without proper assistance.
We have run some basic tests to try to hint at what the substance may be, but I will need your help in narrowing it down.
We have done a flame test, and the flame burned at an orange/yellow flame, although my group swears they see a tiny hint of purple now and then, but I believe that is just paranoia sinking in form our approaching deadline.
We have also done a percipitate test, and we had results that hinted at the fact that our substance has Chlorine in it because the test tube was filled with clumps of a white flaky material, and the water became hazy. We conducted this lab with Silver Nitrate, we placed our unknown substance in a test tube, and we put a few drops of silver Nitrate into it. And the above percipitate formed.
In additon to that, we did a conductivity test. Which was a test in which we hooked up copper wiring to a battery, and placed these positively and negatively charged wires into our unknown substance, which we poured onto a watchglass. After a while, green colored clumps began to form in the pool of our unknown substance. And the water took on a slightly gray tint to it. We also clipped a light bulb onto the copper wiring to see if the compound we had was covalent or ionic, the lightbulb didn't light, so we assumed that the compound is either a very weak Ionic bond or a Covalent bond. But remember, our substance has been significantly diluted, it is about 90 percent water and 10 percent substance, and I believe that is why the lightbulb did not light.
Finally, we conducted a PH test and the PH of our substance was 7.
Now, our unknown substance is one from this list...
Sodium Borate.
Potassium chloride.
Calcium chloride.
Or Sodium chloride
I humbly ask you for assistance... and contribution would be greatly appreciated.
