Acid Essay Examples
Introduction In the experiment preformed the objective is to titrate a weak acid with a strong base. In a titration of a weak acid with a strong base the titrant is the strong base and the analyte is a weak acid. The reaction that will occur is the direct transfer of protons from the weak…
The results of the soap tests indicate an unsuccessful synthesis of soap. Minimal amount of foam was observed from any the tests. It was expected that foam would be presents in DI water, but decreased in CaCl2 or Trisodium because it makes the water a “hard water” and causes the soap precipitate, make it ineffective….
Fluid Compartments Water occupies two main fluid compartments Intracellular fluid (ICF) – about two thirds by volume, contained in cells Extracellular fluid (ECF) – consists of two major subdivisions Plasma – the fluid portion of the blood Interstitial fluid (IF) – fluid in spaces between cells Other ECF – lymph, cerebrospinal fluid, eye humors,…
ABSTRACT In this experiment, the vitamin C content of a commercial tablet is determined and compared with the manufacturers’ specification. Vitamin C is water-soluble and is an enantiomer of ascorbic acid. (Commercial vitamin C is often a mixture of ascorbic acid and other ascorbates.) Ascorbic acid, C6H8O6, is a reducing agent that reacts rapidly with…
1.What are the significant regions in the titration curve? Relate the characteristics of each region to the pH results obtained. -There are four significant regions in each titration curve, namely the initial, pre-equivalence, equivalence, and post-equivalence points. These points are named according to its position relative to the equivalence point. The equivalence point signifies the…

ABSTRACT High Performance Liquid Chromatography has been used to evolve an analytical procedure for the evaluation of the content of paracetamol in the bulk, dosage forms and in urine, a body fluid. Separation and resolution have been achieved with a combination of methanol and 2.5% acetic acid (15:85) on a reversed-phase column at ambient temperature….
Republic Act No. 9275 Philippine Clean Water Act of 2004 is an Act providing for a comprehensive water quality management and for other purposes. In Section 2 of this Act, it states that the State shall pursue a policy of economic growth in a manner consistent with the protection, preservation and revival of the quality…
Research Question: How does the concentration of carbon dioxide affect the rate of photosynthesis in spinach leafs? Introduction: Spinach is a eukaryotic photoautotroph, contains plant cells and appears to be green, this suggests that it contains chlorophyll given that chlorophyll reflects green light (Mazia & Tyler, 1963). Photoautotrophs are organisms that use photosynthesis to sustain…
Experiment 1: Bromination of Acetanilide1 Precautions: Ethanol is flammable Sodium hypochlorite is an oxidizing agent and releases toxic fumes (handle in fume hood) Acetic acid is corrosive, harmful if inhaled, flammable and can cause burns (handle in fume hood) Gloves are recommended to avoid chemical contact with skin Reaction Scheme: Conversion of acetanilide to p-bromoacetanilide…

Bromine test 1.6 clean and dry test tube were taken and were labelled them A until F 2.1ml of dichloromethane were placed into each test tube 3.1 ml of cyclohexane were placed into tubes A and B,1 ml…
Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment, the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate…
