Flame Test Lab

I wasn't here when my class completed the flame test lab, so instead, I looked it up online.

"A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic emission spectrum. The color of flames in general also depends on temperature."

A flame test involves the elements on the periotic table, and what makes up the elements.  From what I've seen online, all the elements basically have a color and when one does the experiment with the elements, it causes all the flames to turn different colors.

A flame test is used to determine the identity or possible identity of a metal or metalloid ion found in an iconic compound.  It's used to visually determine the identity of an unknown metal of an iconic salt based on the characteristic color (like what I said before, all the elements have their own colors), then the salt turns the flame a different color on the Bunsen burner.

Law of Conservation Mass

1. Color changed, it thickened, and produced a gas

2. It changes with the changes with make to the reactant.

3. The mass is not conserved because with each experiment and each time we tried it, it was a different mass every single time therefore it was wasted because it was never the same.

Scientific Skills Lab - 1

1)      The water turned blue because we stirred vigorously after about five minutes after putting the copper chloride in the water.

2)      When solutions are made, different results could come out.  A solution is whenever you dissolve something into a liquid, in this case, the water and the copper chloride.

3)      I think what happened is that when the aluminum reacted with the copper chloride, the copper chloride was eating away at the aluminum, forcing it to change into a copper form.

4)      When the nitric acid reacted with the precipitate, I think what happened is that the nitric acid made the copper turn into a liquid, forcing it to bubble and become clear, like the nitric acid was cleaning or filtering the copper precipitate.

5)      The solution turned blue at the end of the experiment because it was bubbling into the blue after we put in the nitric acid.
