Pretty, pretty pH!

So I've had this set up for awhile, not sure why I didn't post it! Just some pretty pictures of our experiment with pH and pH indicator dyes :).

Virus Insanity Swatches, part 2!

I recently acquired six more amazing VIE eye shadows, this time in a neutral variety! :) I decided to swatch and share, and I also included one shadow that I missed in the last round of swatches, Insanity.

The package arrived wrapped up tightly, in a bright blue bag! As always there are labels with the name, and an ingredient list on the bottom, with sifter stickers that didn't budge! :) I got Simple Highlight, Warm Highlight, Tenderheart Bear, Friend Bear, Mew, and Wicked Kisses.
Simple highlight is amazing, you can pack it on to get a bright white, or blend it out to get a subtle shimmer.

Above; Simple Highlight blended out some.

EOTD: The lost looks! 6/6, 6/8, 6/14, 6/15, 6/20, 6/21

So school has been taking up all of my time, making me feel lazier than normal! So I have missed quite a few looks from the past few weeks. This will be an EOTD overload! I'm not sure if I remember every single look, but I'll try my best to name all the products used. 

For the above look I used a TKB green, Burnt by VIE, and an Aromaleigh Ooops! brown.

The above is a green sample that I cannot remember the name of, and then I know it's Damask by ARC with a black layered on top of the edge.

Above is Perverse by VIE, then Amy by Altered Egos, and I believe Rainbow Moon Heartache by Persephone.

Above I'm wearing all Aromaleigh Oops! colors except the white. 

Above I'm wearing Magnolia by Aromaleigh, Burnt by VIE, and an Oops! by Aromaleigh. :) These colors made my eyes POP! like crazy!

Above, no products! Simple some black eyeliner. :) I was very, very lazy today. Haha.

Experiment 40, Ten Test Tube Mystery

This experiment was harder to set up for than it was to actually do. So, we were given 10 different solutions. Of those 10, 3 were identifiable by either color or smell. So our goal was to find the other 7 through a series of tests. First we had to create a reaction table. That is, we set up a ten by ten table, and indicated the reaction between each of the 10 solutions. Which looks like this;







NR means No Reaction, P-Precipitate, 'P, D'- Precipitate then Dissolves, Slight P- Slight Precipitate

This was our first lab day, it took us a minute to compare each and every cation and anion to see what would happen in every reaction to identify if there would be precipitate (A solid substance formed between our two aqueous solutions), slight precipitate, or would form a precipitate and then dissolve as we added more of a solution with their ligands (something that forms a complex with the solution and basically prevents it from precipitating). We also knew that all of our bases and our acids would create heat, with no precipitate. Another identifier we were looking for was smoke, which is a reaction that occurs between HCl and NH4OH.

This was my groups set of chemicals. We had HCl-hydrochloric acid, H2SO4-Sulfuric Acid, SnCl4-Tin Chloride which was in a HCL solution, NaOh-Sodium Hydroxide, Ni(NO3)2-Nickel Nitrate, Al(NO3)3 Aluminum Nitrate, AgNO3- Silver Nitrate, Ca(NO3)2-Calcium Nitrate, Cu(NO3)2- Copper Nitrate , and NH4OH-Ammonium Hydroxide.

This was the other set, I have no idea what they are. :)

This was our first test. We had to determine the solutions with at least five steps. This was my thought process, but we discussed everything as a group. First, I wrote down what each of the three solutions that we knew were by direct observation. Then I wrote down what each of the solutions reacted with. The nickel nitrate and the copper nitrate only reacted with sodium hydroxide and ammonium hydroxide. We decided to test with copper nitrate. Since we also already knew the identity of ammonium hydroxide and nickel nitrate, we only needed to test the other 7 solutions. We added each unknown solution into it's own test tube, then added a little copper nitrate to each and looked for a precipitate. What was interesting is that the precipitate took all the blue out of the solution! Really cool looking. Here's my really bad paint example.

Above is supposed to be adding copper nitrate, which is blue, to 7 clear solutions. All of the samples except sodium hydroxide would just turn a diluted blue. Sodium hydroxide however would form a blue precipitate, taking all of the color out of the solution. Next we wanted to find out which were the acids. We also had the tin chloride which was in a hydrochloric solution, but we also knew that would form a slight precipitate. Hydrosulfuric acid and hydrochloric acid would just create heat with sodium hydroxide. We were also able to identify silver in this test because it creates a brown precipitate.Then to identify what which of the two solutions, that created heat when mixed, were which, we mixed them both with ammonium hydroxide. As I mentioned before, one of our identifiers was that hydrochloric acid and ammonium hydroxide would create smoke. The last two solutions we needed to identify would be aluminum nitrate and calcium nitrate, and to decide which was which, we added more sodium hydroxide to each of the unknown test tubes. Both form a precipitate with sodium hydroxide, but when enough is added to aluminum nitrate, then the precipitate disappears, where as in calcium nitrate the precipitate will be murky, but will still persist.

So there you have it! The super boring post of how to identify ten liquids by their reactions and by direct observation. :)
