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

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Caffeine is a xanthine alkoid compound that acts as a stimulant. In humans‚ caffeine can help with alertness and wards off drowsiness. Caffeine can be found in cocoa‚ coffee beans‚ and tea leaves. It can also be found in over the counter medication. One of the newest sources of caffeine are energy drinks. Many people drink caffeine making it very popular and a widely consumed product. Over 90% of the population consumes caffeine. Even though caffeine is very popular it has some negative effects to

Determination of citrinin produced by P. notatum and A. nigerin liquid media The filtrates obtained from above experiment were used for extraction and estimation of citrinin. Briefly‚ the citrinin was extracted thrice with chloroform (1:1 v/v). All the three extractions were pooled and concentrated in vacuum at 40°C using a rotary evaporator. The crude extract was then diluted in minimum amount of chloroform (2ml) and citrinin was estimated by thin layer chromatography (TLC) according to Razak et

target and analyze only the phosphate-AVM complex while yielding the least impact from the potassium ions. As for the colas‚ they are made with so many ingredients that it was very important to have a good analytical wavelength. In addition to phosphate‚ there is caffeine‚ sugar‚ corn syrup‚ vanilla‚ and many other ingredients in colas (Field); all of which could have an effect on a percent transmittance reading from the Spec 20 at a poorly selected wavelength. Using the analytical wavelength minimizes

Coffee has become a huge consumption in the world today. There is so many different things that coffee has done in the world today. There are many different situations where coffee is very important in the world. One example can be seen is from the people in Ethiopia where there is a huge dependence of harvesting coffee beans and the fact that it is Ethiopia’s major exports that they have. Another example that can be seen is in North America where the majority of people would drink coffee as a
