* What is this substance This substance is iodide Confidence Report The aim of extraction, is to separate a part of raw material, using a solvent such as water with heat. A tincture of iodine is a common medicine sold in many pharmacies, used as an antiseptic on cuts of the skin. The objective of the seaweed lab, is to produce a tincture of iodine by extracting Iodide and other components (seen when a mixture of iodine is present), from seaweed. We
However, the alcohol remains fairly constant in the form of glycerol or in other words propane -1,2,3- triol. This form of alcohol contains a hydroxyl allowing longer chains to form of carbon. 7. A common commercial use for esters is in the perfume industry where a synthetic scent is created within labs through the process of esterfication. For example, Benzyl Acetate is one form of an ester that can be used as to create a perfume
The separation of cyclohexene could not depend on distillation alone. The method used in our experiment is one way that we could employ to separate azeotropes into its constituents. By adding a chemical that could form complex with one of the component, in our case, CaCl2 forms complex with water,
2.2 Cleaning agents should be used to prevent infection and to follow any organisational policies and COSHH regulations. Cleaning agents include soap-based detergents and can be used for floors, walls, fixtures and fittings and persons. 2.3 Disinfecting agents generally include chemical detergents that are antibacterial or antiseptic and are used for the disinfections
Acetanilide is also used as an intermediate for the synthesis of rubber accelerators, dyes, and is used as a precursor in penicillin synthesis. The melting point of the base was determined to be between 80-87 degrees. Based on the melting point we identified the identity of our base as Ethy-4-amiobenzoate. Ethy-4-amiobenzoate is an anesthetic which is applied topically to the skin and mucous membrane and is also used to suppress the gag reflex in various
calls us again in. We make sure that she has wiped and also sometimes help her if she cannot reach. Afterwards we apply Conatrone or Sudocream as barrier creams to protect her groins and skin. If she needs to wear a pad, we help her put oune on. Then she is pulling up the front part of her underwear and trousers and we make sure that they are up on the back also.
After being individually preserved, the organs are stored in a canopic jar. The lids of canopic jars are shaped like the heads of Egyptian gods, the four sons of Horus. 7. Now that the drying process was complete, the bags of natron that had been placed inside the body could be
ANCIENT PERIOD While no one knows when beverage alcohol was first used, it was presumably the result of a fortuitous accident that occurred at least tens of thousands of years ago. However, the discovery of late Stone Age beer jugs has established the fact that intentionally fermented beverages existed at least as early as the Neolithic period , and it has been suggested that beer may have preceded bread as a staple ; wine clearly appeared as a finished product in Egyptian pictographs around 4,000 B.C. . The earliest alcoholic beverages may have been made from berries or honey and winemaking may have originated in the wild grape regions of the Middle East. Oral tradition recorded in the Old Testament asserts that Noah planted a vineyard on Mt.

Pictographs are rock drawings. Petroglyghs are rock carvings. These early people left both pictographs and petroglyghs that date back more than 11,000 years. To paint pictographs (rock drawings), the Ancient Ones used twig brushes dipped in naturally colored vegetable fats. These early people painted hands, animals, dancers, hunters, gods, and medicine men.
