    Acid Base Titration

    • 738 Words
    • 3 Pages

    Introduction Acid-base titrations are used to calculate properties of an acid or a base by titrating them with a strong Acid or base. In a titration, certain amount of volume of one substance usually a strong acid or base, a titrant, is added to another substance, an acid or base of some kind, until a change in properties are observed. Strong acids and bases are used because they allow the neutralization reaction between the acid and base into salt to go to completion. By titrating an unknown concentration of acid or base with a known concentration of acid or base, you can calculate properties such as the concentration and pKa of the analyte. During the standardization part of this reaction, we are adding Sodium Hydroxide, NaOH to a solution…

    Problem Statement: How do different amounts of soil affect the pH of water? Is the relationship the same for different types of soils? Background: PH is a measurement of how many ions of hydrogen are found in a solution. The pH scale measures how alkaline or acidic an object is. The scale has numbers ranging from zero (which are considered the most acidic) to fourteen (the most alkaline, otherwise known as the most basic). Pure water has a pH of seven, however most water, either from the tap or…

    • 7 Pages

    RESULTS Phytic Acid The concentration of phytic acid was determined spectrophotometrically in three tested plant materials of Gishta as shown in table 2. The concentrations of phytic acid were obtained from 5 g dried leafy material. All the leaf samples contained phytic acid (detection limit 0.025 mg/ml) in this study. This may have been due to the fact that there was a limitation in terms of the detection concentration since concentrations less than mg was not tested. Seed extracts was found…

    • 2 Pages

    In this experiment, the goal was to figure out which solute would be the best at neutralizing stomach acid the quickest. As baking soda was added to stomach acid, then the time for neutralization was the quickest. From the data chart, baking soda had the largest average pH of 6.6. On the graph, it show how baking soda had the highest peak and how it was the closest to reach 7 than any other substance. The hypothesis is supported because baking soda was the antacid that was closest to…

    • 4 Pages

    Acid rain is any form of precipitation that is extremely acidic, causing harmful effects on the environment. The unusual acidity of acid rain is caused by the high levels of nitric and sulfuric acids in the atmosphere, generated mostly by human activities but also by natural activities. This document will describe the process of acid rain from creation to the effects it has on the environment. Chemical Sources In the formation of acid rain, natural and human-made sources are known to play a…

    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…

    Polylactic Acid Plastics have played a major role in shaping modern society, ultimately improving the quality of life. Making up most things man-made, plastics surround us every day. They possess unique characteristics; plastics can be tough and rigid yet still flexible and can be opaque yet transparent. The building blocks of plastics are small organic molecules often known as monomers, which then join to other monomers creating long molecule chains called polymers in a process called…
