their compounds. Common catalysts include manganese dioxide‚ silver‚ and platinum. The same reaction is catalysed by the enzyme catalase‚ found in the liver‚ whose main function in the body is the removal of toxic byproducts ofmetabolism and the reduction of oxidative stress. The decomposition occurs more rapidly in alkali‚ so acid is often added as a stabilizer. The liberation of oxygen and energy in the decomposition has dangerous side-effects.

trans-isomer fatty acid. Because the term refers to the configuration of a double carbon-carbon bond‚ trans fats are sometimes monounsaturated or polyunsaturated but never saturated. Hydrogenation‚ to treat with hydrogen‚ also a form of chemical reduction‚ is a chemical reaction between molecular hydrogen and another compound or element‚ usually in the presence of a catalyst. The process is commonly

Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the reduction of I2 into I-. Between these two methods‚ iodometry is more popular because it

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

When indigo is reduced‚ it forms leucoindigo. Indigo is a blue dye while leucoindigo is colorless. Below is the equation of the reduction of indigo: In order for indigo to be used‚ it needs to be reduced into leucoindigo because indigo is highly insoluble while leucoindigo is water-soluble. When fabric is soaked in leucoindigo and then allowed to be air dried‚ the exposure to the

Diabetes Insipidus Abstract This paper covers the basic pathophysiology of the disease process for diabetes insipidus. It is also a preview of the most common symptoms of the disease‚ and the treatments associated with it. One treatment is vasopressin which is an antidiuretic. Another treatment option is Chloropropamide which is used to aid in the control of diabetes mellitus type two‚ but can also be used to aid in the assistance of controlling diabetes insipidus. Lastly there are
