oil‚ glucose solution‚ sucrose solution‚ starch solution and distilled water were added separately into six marked test tubes. The volume added was about one finger thick in depth of a test tube. 2. 5 drops of Iodine solution was added to each test tube. 3. The sample’s reaction with iodine was recorded. 4. The samples connected by another group with 5 drops of Benedict’s solution added were heated all together in hot water bath. 5. The test tubes containing samples were taken out of the hot water

Most known compounds in living organism are if fact carbohydrates‚ lipids‚ proteins

function of the mordant iodine in a Gram staining procedure? A mordant causes the crystal violet to run. A mordant fixes the bacteria to the slide. A mordant keeps dye attached to an object. All of the above 5. What is the order of reagents used in the Gram stain? crystal violet‚ iodine‚ safranin‚ alcohol alcohol‚ crystal violet‚ iodine‚ safranin iodine‚ crystal violet‚ safranin‚ alcohol crystal violet‚ iodine‚ alcohol‚ safranin crystal violet‚ safranin‚ alcohol‚ iodine 6.

Bactine Original First Aid Liquid (Bactine)‚ and Povidone-Iodine Solution‚ 10% Topical Microbicide Antiseptic (Iodine) are an appropriate antiseptic to can kill a sample bacterial contaminant found in the local environment‚ and if so‚ which is the most effective? The purpose of this experiment is to determine the antibacterial effectiveness of Scope‚ Listerine‚ Bactine‚ and Iodine in relation to each other. Scope‚ Listerine‚ Bactine‚ and Iodine each are believed to be effective antiseptics: * Scope

Hashimoto thyroiditis respond better. * Treatment of hypothyroidism or hyperthyroidism often reduces the size of a goiter. * Thyroid hormone replacement is often required following surgical and radiation treatment of a goiter. Use of radioactive iodine for the therapy of nontoxic goiter has been disappointing and is controversial. * Medical therapy of autonomous nodules with thyroid

Benedicts Reagent Methods In this lab there are I complete two different tests. The procedure was relatively the same for each test. I would first add 3ml of a given substance to a test tube‚ followed by 5 drops of either Biuret Reagent or Iodine. Once the agent is added‚ I swirled the two substances and then observed the results. The first was to test proteins‚ and

Grouping elements with similar chemical properties together Date: 4.10.2012 Objectives The objective of this experiment is to experimentally investigate which elements show similar chemical properties. Chemical principle Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a dull gray‚ silver solid under standard conditions. Calcium atoms have an electron configuration of (2‚ 8‚ 8‚ 2) and 2 outermost shell electrons. Calcium is in group 2 and period 4 of the

Benedict’s solution is added to each test tube. Both test tube are heated together in the water bath for two minutes. The result is recorded in Table 1. 2. A few drops of fresh solution A and B are added separately spaced on a white tile. 1-2 drops of iodine solution are added on each solution. Observations are recorded in Table 1. 3. 2 ml of solution B is pipetted into each of four boiling tubes. The tubes are labelled 1‚ 2‚ 3and 4 respectively near mouth of tube. 4. Tubes 1 and 2 are placed in
