Indicator

the acid detergent fibre which is a measurement of lingin, cellulose and lignified nitrogen is 306.79 (g/kg DM). The neutral detergent fibre of the silage was 552.40(g/kg DM) and is an indicator of forage intake potential which declines as NDF value increases. The pH value of the silage is 3.91 and its an indicator of the acid in the silage.…

The endpoints of the pH indicator method were observed at 33.6 mL, 38.8 mL and 44.6 mL respectively. In the visual identification the endpoints were found at 33.8 mL, 39.2 ml and 44. 6 mL these value can be observed in the figures 5, 8, and 11. In the numerical differentiation method…

For the following lab, the purpose is to utilize titration to determine the amount of ascorbic acid (vitamin C) present in a substance by reacting it with potassium bromate. An oxidation reaction takes place with ascorbic acid to produce dehydroascorbic acid, using an excess of bromine. The total amount of bromine utilized during the experiment is determined utilizing a back titration, in which the bromine is reacted with bromate. One mole of bromate produces three moles of bromine and the…

coordinate the recruitment, retention and development activities (Boxall 2011) of warehouse staff. In addition to a daily communication of the IFOT metric to several stakeholders, which can be used for workforce planning in an ongoing manner as a lagging indicator. 7.2 Hussmann Weaknesses The weaknesses…

Question 1 a. Public Health Indicator: A public health indicator can be quantifiable as it is used as a supporting evidence when the health status of a population is been described. Public health indicator is a summary statistics of which is directly related to and which facilitate concise, comprehensive and balanced judgements about the condition of a major part of health or the progression towards achieving a healthier society. An indicator is known to simply measure hence it is a measure of…

ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…

The Myers-Briggs Type Indicator (MBTI) is an assessment/survey that is intended to evaluate how individuals perceive the world around them and how they come to conclusions when making decisions. The MBTI suggests that there are 16 different types of personalities. The test is made up of a series of 64 questions and the answers to these questions will determine which of the 16 personalities you have. The test will also provide you with general assumptions (generalizations) about what job is best…

After thymol blue was added, the pH-buffered samples developed the colors of red, yellow, green, and blue as the pH of the solutions increased (Figure 3.1A). The pH-2 buffer turned to a light red-pink color, while pH-3 to pH-6 displayed very similar forms of rich yellow or light orange (Figure 3.1A). The neutral pH buffer solution appeared as a saffron green colored solution (Figure 3.1A). A mixture of yellow and green was apparent in the dijon color of the pH-8 buffer (Figure 3.1A). The buffer…

Project 3 Identification and Synthesis of an Unknown Ionic Compound Mitchell Morgan CEM-161-007 Josh Ward 28th October 2015 Abstract The chief objective of this experiment was to identify the unknown compound. The following tests were conducted to eventually establish the identity of the compounded: qualitative solubility tests, anion and cation tests, flame test, and the formation of a precipitate. The physical properties of the unknown ionic compound found that it has no smell and was…

Lab 14/ Test 6: Determination of Acid Dissociation Constants through Titration Sabrina Tom I.Abstract The two unknown solutions A and E were titrated with NaOH solutions. For each solution, one fast and three slow titrations were done to see where the pH rose exponentially. The unknown solutions A and E were determined to be Pyridinium ion acid and oxalic acid, respectively. II.Theories One significant concept throughout this lab is titrations. A titration is a lab method analyzes a…
