Interpretation and Evaluation: Rinsing Process: When performing a volumetric analysis all equipment to be used must be washed with deionised water. This is done in order to remove anything that contaminate your solution and have an effect on the results. It is important that deionised water is used and not regular tap water, this is because tap water could itself contains many unwanted impurities such salts, other solids and bacteria. If these were to contaminate the solutions to be used it…

personality, though it does not seem that difficult, is actually quite arduous. The Myers-Briggs Type Indicator is a tool developed to help the average person determine their personality.

The Myers-Briggs Type Indicator is a tool that, though it has a few problems, does an astutely accurate job of…

The Myers-Briggs Test Indicator, or the MBTI, is a self-inventory designed to identify a person’s personality type, strengths, and preferences (Cherry, N/A). A woman named Isabel Myers and her mother, Katharine Briggs, composed this list of questions based on their work with a psychoanalytic psychologist, Carl Jung’s, theories on personality types (Cherry, N/A). After taking the test, people are told to have one out of sixteen personality types, and four out of eight personality traits. These…

metals and can turn them into salt, such as calcium, turns red on blue litmus paper, is corrosive or sour-tasting when it comes to liquid, generates pain in wounds, and turns colorless when placed in phenolphthalein which is used as a basic to acid indicator ("Definition of acid in English:"). Alkalis is any kind of substance that can produce OH ions, hydroxide ions, in water, which can also be known as 'basic', or 'basicity' ("GCSE CHEMISTRY - What is an Alkali? - What is a Base? - GCSE…

bromthymol blue, and an elodea plant in an environment with light, it will result in a color change from yellow to greenish blue. Also, if a sealed test tube containing bromthymol blue and an elodea plant in a dark environment. The bromothymol blue, a pH indicator, was used to measure the amount of CO2 present in a given test tube. The controls being tested were two negative controls that consisted of one test tube containing bromothymol blue, CO2, and an elodea plant while being in a dark…

Sodium hydroxide, buffer solution, bleach, and the detergent were found to be basic…

Danika Ng CHEM 1252 L Exp 12: Thermodynamic Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of…

area, with 4 in Springfield proper. However the census tract that overlaps the Mason Square neighborhood has the most highly concentrated factors for this issue by meeting all of the leading indicators for food access deficiencies. This is demonstrated by the results of the USDA Food Access Atlas Indicator Tool shown in Figure 1.1. The following figure 1.2, highlights the difficulty that a lack of mobility presents for the elderly in terms of healthy food access. According to the Pioneer…
