Iodine

When the first bag, which was made of distilled water (10 mL), was fully immersed into distilled water. Its mass almost did not change (Table 1). It increased from 11.9g to 11.3g after 15 minutes, but after it, the mass always kept in 11.3g during the last 45 minutes. For Bag 2, 10mL 10% sucrose immersed into distilled water, its mass increased with the time increased (Table 1). It showed that the weights increased 1.2g in 60 minutes. Also for Bag 3, which contained 30% (10mL) sucrose immersed…

of iodine solution. Calculation of standardization factor Standardization factor = (mass of vitamin C titrated) / (Volume of iodine solution used) = (125g) / (41.3ml) = 3.03 mg vitamin C/ml iodine solution Experiment B: Vitamin C titration using fresh fruit sample to determine the content The tabulated experimental data for this experiment is shown below (Table 2). In this experiment, the amount of vitamin C was calculated by multiplying the standardization factor with a used iodine…

was used to heat water up to 60oc. Pieces of dialysis tubing were wet and had starch solution put inside. Half of the measuring cylinders were filled with 60oc water, and the other half with 25oc water. Tests of the water were carried out with an iodine test and diet stix to detect any starch that had been broken down and passed through the tubing. The results from the tests show that there were experimental errors, and the experiment should be carried out again to…

There are several different diseases and disorders that are caused by the endocrine system. Endocrine systems are made up of a gland that make and also relinquishes hormones that assist in the regulation of body functions. It also essentially helps with the body’s capacity to transition calories that create energy for the cells and also the organs. The endocrine system impacts the way that your heart beats, how the bones in your body as well as the tissues produce. The endocrine system also…

in 1882. This method is now one of the most important staining procedures in microbiology. Steps of the Gram stain: Reagents: • Escherichia coli (slant culture) • Staphylococcus aureus (slant culture) • Crystal violet (primary stain) • Iodine solution (Gram’s iodine) • Decolorizer (ethanol) • Safranin (counterstain) • Water (in squirt bottle) Prepare a mixed smear using slant cultures: 1. Take two…

Triiodothyronine is created by the thyroid gland that is in the throat. The two chemicals used to create T3 and T4 is tyrosine and iodine. Tyrosine is an amino acid that is created in the body and iodine is a naturally occurring chemical element. Then the thyroid starts producing tyrosine, thyrotropin, a hormone, is released and produced by the hypothalamus. In the hypothalamus, iodine is captured by a hydrogen peroxide trap by the thyroid peroxidase and adds to the 3’ and 5’ positions of…

Vitamin C is a an important nutrient which is required in our bodies, taking in large amounts of vitamin C causes stomach aches, diarrhoea and flatulence(gas which is generated in the intestinal tract) It helps protect cell and keep them healthy it is also needed to heal the wounds. An adult is required to have 40 mg of vitamins a day,Vitamin C cannot be stored your the body, so you must have vitamin C in your everyday diet.If you don't have enough vitamin C in your body you can get…

patients undergoing clean-contaminated surgery, the intervention is preoperative skin preparation, the comparison of is povidone-iodine skin preparation, and the outcome is the reduction of SSIs. Three online databases were used as the search strategy: Wiley Online Library, MEDLINE with Full Text, and CINAHL Plus with Full Text. The key terms were “chlorhexidine” OR “povidone-iodine” AND “clean-contaminated” OR “surgical site infection*” AND “skin preparation”. The language choice was limited…

(1-propanol, 2-propanol) ethanol and mixtures of alcohols act as good antiseptics. These alcoholic solutions commonly known as surgical alcohol and used for disinfection of skin before injection is used along with other antiseptics like tincture of iodine and chlorhexidine. 2. Quaternary ammonium compounds: These compounds can act as antibiotic as well as antiseptics also. For example; Benzethonium chloride. These compounds are commonly abbreviated as "Quats," and used to sterilize the skin…

Lugol’s iodine and Acetic acid in the detection of potentially malignant disorders (PMD’S). Materials and methods: The study population consisted of 30 patients with clinically suspicious PMD’S. The lesions were stained consecutively with toluidine blue, lugol’s iodine & acetic acid depending on the retention of the dyes, the biopsy site was determined and sent for histological confirmation. Statistical Analysis Chi-square test was used to compare between Toluidine blue, Lugol’s iodine and…
