Determination of Ka for a weak Acdi

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…

Soaps and Detergents

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, Electrolyte, and Acid-Base Balance: Introduction to Body Fluids

  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,…

Determination Of Vitamin C Content Of Tablet

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…

Titration Curve

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…

Difference in Lymphatic Function in Health and Disease State

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….

Effect of Different Concentrations of Carbon Dioxide on the Rate of Photosynthesis in Spinach leafs




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…

Testing the Ph of Common Household Substances Lab

Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution, 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral…
