Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration method. The KHP solution

RESULTS AND DISCUSSION A redox titration involves the transfer of one electron from one reactant to another. The two reactions happen simultaneously.1 This experiment employed titration involving the use of iodine. Iodometry is the titration process where iodine is used as titrant for strong reducing agents. Another type of titration where iodine is involved is called iodometry‚ where iodine “is produced in-situ from the quantitative oxidation of iodide and then subsequently titrated with thiosulfate

Preparation and Ferroelectric Characterization of Calcium doped Barium Titanate ceramics ABSTRACT Barium Titanate (BT) is widely used in electro-optical and electroceramic industry because of its ferroelectric‚ thermoelectric and piezoelectric properties when it assumes the tetragonal structure. In addition to its Lead free composition‚ its perovskite structure allows variation of ionic size and small displacement of atoms that lead to the distortion of the structure which has a profound

what is happening when lower back pain strikes‚ the patient needs to understand the structure of the spine at lower back level. Each of the parts of the spine represents important facets when trying to combat pain and an explanation will make that understanding easier. This area is called the lumbar spine. Image source: Lumberspine.net As can be seen from the image‚ the lower back area is complex and made of many different components. Thus the complication of lower back pain is increased. The bones
