Experiment: Materials: -2 graduated cylinders -4 food colorings -something to stir with -1 beaker -50 mL of water -25 mg of salt -scale to measure salt -timer Procedure: measure 10 mg of salt in the scale and put it in the bottom of the graduated cylinder before putting in anything else measure 50 mL of water and put it in a beaker add 15 mg of salt to the 50 mL of water and stir it until it is completely dissolved carefully put 10 mL of the saltwater in the graduated cylinder with the salt in the bottom put 2 drops of food coloring in the saltwater that is in the graduated cylinder wait about 1 minute until that saltwater layer is completely colored add 10 mL of water to the beaker that has saltwater in it so that the salinity of the water decreases. stir. carefully pour the water with less salt into the graduated cylinder that has the other layer(s) add 2 drops of another color to the new layer that has less salt and wait 1 minute a second layer should me forming repeat steps 7-9 so that more layers can be made Observations: the new layers take some
The last one was nickel (II) nitrate I placed 2 drops into seven of the E well plates of the 96 well plate. In the next step going vertically, I started with sodium phosphate solution and placed 2 drops into 5 vertical rows. The next one was sodium iodide solution I placed 2 drops into 5 vertical rows. The next one was sodium sulfate solution I placed 2 drops into 5 vertical rows. The next one was sodium bicarbonate solution I placed 2 drops into 5 vertical rows.
6. Wait for 5 minutes and observe results. 7. Clean out the Petri dish Repeat steps 1-7 Results: Type of Milk | 5 minutes after addition of food coloring | 5 Minutes after addition of food coloring | Fat Free Milk | The food coloring slowly spread into large circles that had a large light color ring around the outside of the circle and a darker center. There were a few shoots of darker color from the centers of the circles into the lighter color ring.
Add 1 drop of phenolphthalein to wells C1, C2, C3 and C4. Stir with a clean toothpick. 5. Add 5 drops of 1.0 M NaOH, sodium hydroxide solution to wells C1, C2, C3, and C4. Stir and observe.
I added 1 drop of phenolphthalein to wells C1, C2, C3 and C4 and stirred them with a clean toothpick. I then added 5 drops of 1.0 M NaOH, sodium hydroxide solution to wells C1, C2, C3 and C4 and stirred them. Cells 1 and 2 turned a dark pink while cells 3 and 4 were a lighter pink. Cells 1 and 2 would have a shift to the right and be
