Extraction Report For experience 4c we were supposed to determine which one is the organic layer in three different tubes that has two layers. To determine which is aqueous (water) or organic‚ I used the technique of adding droplets of water to each tube. If the layer is water‚ then the drops of added water will dissolve in the aqueous layer and increase it’s volume. If the added water form droplets or a new layer‚ then it is the organic layer. Tube 1 (water and n-butyl chloride)‚ after adding

TITANIUM EXTRACTION ASSIGNMENT 1 1.TiO2+Cl2-----------------TiCl4+O2 2.Why is an atmosphere of argon used for this reaction ? The titanium (iv) chloride is added to a reactor in which very pure sodium has been heated to about 5500c -everything being under an innert argon atmosphere.During this reaction the temperature increases to about 10000 c . The reaction is carried out in an argon atmosphere to prevent magnessium and sodium from reacting with oxygen in the air. 3.Another gas used instead of

The green leaves Leaves look green because of the chemical chlorophyll. The other reason is that they reflect light in the green spectrum. Chlorophyll absorbs light most strongly in the blue portion of the spectrum‚ and then some in the red portion. Leaves receive their green color during the process of trying to absorb energy from the sun. The sunlight strikes the leaves‚ which contain chlorophyll‚ and the chlorophyll reacts by emitting the green color. Leaves are green because that is the

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides

Variagated Leaves Total absence of plastid pigments causes a sector of a leaf or stem to have white patches. This condition is termed variegation (Metrosideros). Variegation is produced when there is a cell mutation (cytological chimera)‚ and all cells produced from that mutant mother cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are

Extraction of Eugenol from Cloves 02/01/2014 CHM2210L University of North Florida Abstract Eugenol is found in the essential oil of cloves and has distinct properties that make it an important product to both food and drug industries. (Bhimrao‚ et. al‚ 2004). To utilize many of eugenol’s characteristic properties‚ it is necessary to isolate this organic chemical from the other components of cloves. In this experiment‚ eugenol was isolated from a sample of cloves using a series of techniques
