Acid mine drainage

Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

Both IR and UV spectroscopy are methods of measuring the wavelengths absorbed by a tested material. IR spectroscopy measures the absorbance of the tested material in the infrared spectrum, the section of the electromagnetic spectrum with a lower frequency than that observed in the visible light spectrum. Conversely, UV spectroscopy measures the absorbance of the tested material in the ultraviolet spectrum, the section of the electromagnetic spectrum with a higher frequency than that observed in…

In the results of the first trial, two lemons were used and the light bulb did not turn on. The voltage was 1.72v. When 4 lemons were used, the light bulb still did not turn on. The voltage was 2.89v. Then, with 6 lemons, the light bulb finally turned on. The voltage was 3.96v. The average voltage for trial one was 2.86v, and the range for trial one was 2.24v. In the first trial, the mode was not applicable. In the results of the second trial, two lemons were used and the light bulb did not turn…

Kale is such a powerful food to eat that more people should definitely be consuming. It's more prevalent in markets and in society, and still, a lot of people don't know much about it. Here are more fun facts about the plant that most people aren't aware of. Number Eight: It Hides Well Although kale is often known to some people as a very bitter plant, the kind of bitter it is scientifically able to be covered. Unless you fall into the category of being a "super taster", where bitter flavors…

rate is magnesium and hydrochloric acid. Initially, it was hypothesized that the reaction with hydrochloric acid would have the fastest reaction rate due to its high acidity observed from the pH scale. From there, the following reactions were based on the pH of the acid involved as well as the concentration of hydrogen ions/atoms within the acid molecule. As a result, it was hypothesized that the sulfuric acid reaction would be the second fastest and the acetic acid reaction would be the…

Topic: Identifying Unknown Substances. Equipments: • 5 test tubes. • 1 beaker of Acid 1 beaker of water • 4-Litmus papers • 2 Pipette bulbs. • 1 robber stopper. • 1 Bunsen burner. • Q-tips(4). • Scoopula. Observation: Which substance is which? Hypothesis: All the unknown substances that we have are soluble in water. Procedure • We had a 4 test tubes filled with small amount of white powder. We labeled each test tube. For example the first test tube was labeled as “Substance A” , the second…

In this investigation, electrolyte content will be measured and compared to the sugar content to give a measurement of how drinks compare in terms of benefit during exercise. The independent variable will be the drink being tested, and the dependent variable will be the electrolyte and sugar content of that drink. Electrolytes are positively or negatively charged ions that are essential for survival. Positively charged electrolytes move towards a cathode, while negatively charged electrolytes…

The unknown compound was composed of small, white crystals as shown in picture 1. The compound was completely odorless, which was tested by simply smelling the compound. Picture 1 (Unknown Compound): The solubility test of the unknown compound determined that the compound was soluble in water (H2O). The other known salts that were tested that were also soluble were all of the sulfates and NaCl. These were the only salts tested, because before this experiment it was determined by the flame test…

〖Na〗^+and K^+channel relationship Figure one shows the temporal relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where…

Even people living in not so hot places search for information on how to stop armpit sweating effectively. The reason for this information search is because of problem of excessive perspiration called Axillary Hyperhidrosis. When a person suffers from hyperhidrosis excessive sweating is seen in some or several parts of the body even under normal cool atmospheric conditions. This problem happens because of an overactive sympathetic nervous system in some parts of the body. The over activity…
