Sulfuric acid

other one was in a plastic container like the other. Once the water had made contact with the dry ice the ice started to make fog. The fog came from the dry ice when the water met with the ice and made fog. This kind of reaction was, “Carbonic Acid.” This reaction was caused when the two substances have made physical contact. The process of the reaction is when a chemical compound

an acid and a base would have on the pH of a buffer and a non-buffer. We utilized phosphate, a buffer, and sodium chloride, a non-buffer, as our base solutions and added hydrogen chloride, an acid, and sodium hydroxide, a base, to each solution separately. First, we took a base pH reading of 40mL of phosphate with a pH meter, then added 1 mL of our acid, HCl, at a time, recording the pH after each drop was added. As depicted in Figure 1 and 3, the pH gradually dropped after each mL of acid was

water of the hydrate. Hydrates are solid ionic compounds that contain water that is chemically inside the crystalline structure. An example of such compound is epsom salt. A salt is an ionic compound that forms as a product of a reaction between both acid and base. Water molecules that are incorporated with salt are known as waters of hydration. The waters can be removed from the hydrate with the use of heat, thus, leaving the salt with no water molecules. The remaining amount of salt is referred to

Don’t you always hate when you have the perfect bubble and it just bursts! Well I know I do, which is why I am going to find a way to make square bubbles last longer. I have always wondered if you could make different shaped bubbles and now I will finally get to make one myself. My partner is finding a way to make a square bubble so, with her square bubble design, I will add ingredients to make the bubble last longer. I have always loved bubbles as a kid, so I can’t wait to learn more about them

tests, the results were then recorded. It was known that the 10 solutions consisted of 1 M hydrochloric acid, 1 M nitric acid, 3 M acetic acid, 1 M sodium hydroxide, 0.1 M silver nitrate, 0.1 M sodium chloride, 0.1 M zinc chloride, 0.1 M aluminum nitrate, 3 M ammonium hydroxide and 0.1 M lead nitrate, however their corresponding number was unknown. The first identified unknown was 98, acetic acid, given its highly prevalent scent, in addition to it not forming a precipitate with any substance due to

Step 3 Color change (and observations). Blue, the more HCl added, the more blue the chemical has gotten, along with being warmer Step 5 Color change (and observations). Pink, slowly turning from the top to the bottom. Step 6 Color change (and observations). The test tube from step 5 is turning blue, and the one from step 3 stays to blue. Step 7 Color change (and observations). The test tube from step 5 is going to be pink, and the one from step 3 turn pink. Step 8 Color Change (and observations)

For unknown 1, we did 4 dilutions at the 4 concentrations listed in table 3. At 2μl of unknown, triplicate absorbance readings were taken and the average absorbance was 0.6. On the other hand, no further dilutions needed to be done for unknown 2, so three absorbance measurements at 10μl were taken. The average absorbance for unknown 2 at low concentration was found to be 0.37. Since the average absorbance at low concentration for 2 unknowns were found, we used equation 2 below to determine their

The findings of this experiment reinforced the hypothesis that the resting membrane potential is most influenced by the ion potassium. We were able to deduce this through the collection of a multitude of intracellular and extracellular recordings, such as the one shown below in Figure 1. This shows how this experiment was able to record every single resting membrane potential in all three different muscle groups under all six solutions. The fact that potassium is indeed the most influential determinant

Splish, Splash, SPLAT!! The purpose of this lab was to find out if the height at which a droplet is dropped affects the splatter size of the said droplet. If a droplet is dropped from a higher point, then the droplet will have a larger splatter. Materials include: Water Food coloring A beaker that holds at least 50 ml Dropper Paper Pencil Meter stick Ruler Procedure: Add 3 squirts of Food Coloring to your beaker. Add 50 ml of water to your beaker and mix completely. Partially fill the dropper

4 Results and Discussion The results obtained in the three tests described above are consistent with the outcome of similar test settings available in the literature [Daniels et al., 1995,Bano et al., 2009,Capozzoli et al., 2012]. On the one hand, there is the effect of water content in the soil: due to its ability to store and transmit induced energy, water slows down the electromagnetic waves coming from the transmitter and the arrival time is significantly delayed with increasing water content
