For each of the 5 colors, I dipped them onto the correctly labeled dot on the strip of paper and allowed the paper to dry. Repeated this step 3 times for each color. 6. I then created the 1% salt solution. 7. I poured the salt solution into a glass and laid a pencil across the top tooth lass. 8. Then taped the strip of paper to the pencil so that way the water is barely touching the strip of paper, g, Once the experiment has come to a conclusion, I then poured out the solvent and let the strip of paper on the table to dry. 0. Then repeated steps I-g using alcohol as my solvent, instead of the 1% salt solution. Data & Observations I _ I predict the components expect to see from each candy color Will be watered down, mixed and dissolved pigments of each of the candy colors on the strip of paper. 2. 1% Saltwater Solution: Color Length Traveled (in centimeters) Yellow Orange 5 CM Red 4 CM Purple . 5 CM Green 0 CM (No Travel) Alcohol: 3. Observations: a. It was hard to outline and cut the 2 paper strips to their exact measurements. B.
It was hard to place the water equally distant from each other, c, The color from the candies dissolved into the water and disappeared from half of each of the candies. D. The colors began to fade and dissolve from the strip of paper. Using the salt solution, the only colors visible were yellow, orange, green and red. These colors were mixed, meaning there’s more of a lime and turquoise within the colors. E. The dots also became more faded as the experiment went under ay, Discussion & Solution I _ The 1% saltwater solution was easy to create, however there was a greater amount of this solution than the alcohol.
The saltwater solution worked better and had more effect on each of the colors on the strip of paper than the alcohol solution because the colors began to separate, mix, and move further up on the strip of paper, while as the alcohol barely made an effect on any of the colors. The reason for this is probably because water is a pure substance and is more effective on paper than alcohol. 2. I think if I had allowed less time for the lab ND stopped the separation process halfway, do not think the colors would spread, separate or mix on the strip Of paper properly. . The color yellow traveled the farthest on the paper. The colors red and purple traveled the least. The colors yellow and orange remained the same color. Red and purple were mixed together. The color green was dissolved and was not visible on the strip of paper at all It was different when separated by alcohol instead of salt water because the alcohol barely made any effect on the liquid rise on the strip of paper. The 1% saltwater solution allowed the colors to successfully separate the colors.
