    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…

    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…

    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…
