Added 2-3mL of liquid household bleach solution and stirred; solution turned orange. 5. Dipped cotton swab into the salicylic acid hydrolysis solution and wrote a message on a blank piece of flat, white paper and allowed it to dry. 6. Laid the dried message paper on several layers of paper towels for the visualization step to keep the developer solution from soaking on the work surface and surrounding materials.
What do you need? To make the orange peel recipe you will need a tablespoon of orange peel. Also, you will need two tablespoons of olive oil. Method: Mix the previous ingredients well in a small bowl. Then, rub the mixture gently on your face in a circular movement.
Day Two: 1) Gently remove the egg from the vinegar. 2) Using the graduated cylinder measure the amount of vinegar left in the beaker and record it. 3) Record any changes you observe in the egg. 4) After measuring the vinegar pour it down the sink. Rinse and dry out beaker.
Mark the cup with a sharpie with your period number, group initials, and the first soaking solution (water, vinegar, or corn syrup). 2. One group member should take one egg from the soaking container. Each egg should be rinsed under the tap and gently patted dry. 3.
Add two drops of food coloring to the beaker of distilled water and mix thoroughly. Measure out a dropperful of bleach into a plastic pipet and set it aside until Step 8. 6. Calibrate the colorimeter a. Prepare a blank by filling an empty cuvette ¾ full with distilled water.
Don’t worry though; this is not a weapon of assault, but of defense. There will be no throwing of the peanut butter and jelly sandwich, such as in a food fight, to hurt another human being.

Repeat this procedure with the other potato piece, making sure that the balance boat is wiped dry between each weighing. Remove
H2SO4(aq). The three test tubes was picked up gently and placed into the hot bathe gently, and after five minutes the test tube was removed from the hot beaker and was placed into the test tube rack holder. There were three small beakers that contained crushed ice, so in each of those three beakers, the solutions that was inside the test tube was poured into the beaker to get the scent of each final product. Test tube 1 smelled like nail polish remover, test tube 2 smelled like pear and test tube 3 smelled like banana. Theory: Ester is from an organic compound where they are in contact with inorganic salts and they are made out of an organic acid and alcohol.
Then place the agar into the test tube including hydrochloric acid, start timing immediately by the help of a stopwatch. Observe the agar in petri dish; stop the stopwatch when the agar full changes its color to pink, which means that the hydrochloric acid is diffused into the agar completely. Record your data in a table you have made before. Repeat the experiment for each of the different sizes of agar blocks Diagram: Data collection: Dimension | Surface area | Volume | Surface area to volume ratio | Time taken for agar jelly to turn pink | Height=1 cm Length=3 cm Width=2 cm | 22 cm2 | 6 cm3 | 22:6= 3.66 | 2:45:66 | Weight= 0.5 cm Length= 2 cm Width= 1 cm | 7 cm2 | 1 cm3 | 7:1= 7 | 5:12:30 | Height= 0.3 cm Length= 1 cm Width= 2 cm | 5.8 cm2 | 0.6 cm3 | 5.8:0.6= 9.66 | 6:07:41 | Height= 0.6
