Primary chemistry 2013 assessment task #1 the physical process of separating Australian industrial mixtures Iron (FE) is a metallic element which makes up roughly 5% of the earth’s crust. Iron is mined vastly throughout Australia in many different areas including Tasmania‚ South Australia‚ Western Australia and Victoria. Australia is one of the world’s major iron ore producers‚ producing 393.9 Mt in 2009 alone‚ valued at roughly $30 billion. Iron serves many different purposes but it main use

research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is based upon the fact that each component has different physical properties. The components of mixtures are always pure substances‚ either compounds or elements‚ and each pure substance possesses a unique set of properties. Every crystal of a pure substance

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

| Separation of Nitrophenols | | | | Abstract: Using a micro scale steam distillation we separated ortho and para-nitrophenol from a mixture that was already made. After the para and ortho were separated we measured their melting points and compared it to the literature values for purity. For ortho-nitrophenol we had 60% recovery and for para 160% recovery. Our melting point ranges were ortho: 45-46°C and para 64-95°C. Introduction: Nitration: In phenols‚ -OH group strongly

not change color so an additional 0.5 mL of reagent was added and allowed to mix for five more minutes. This process was repeated again and at 40 minutes the reagent was in excess. The reacted mixture was then added to a beaker containing 10 mL of saturated sodium chloride and a small piece of ice. This mixture was then separated equally into two centrifuge tubes where 3 mL of diethyl ether was then added. After gently shaking and venting the centrifuge tubes the bottom aqueous layer was extracted and

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Industrial Separation Blood is a liquid mixture that is found in the biosphere in humans and animals. Blood is always red in appearance‚ liquid‚ and can be thick or thin in texture. The major products of blood are blood plasma‚ white blood cells‚ red blood cells and platelets. Blood has a vital role in our day to day lives and makes it possible for life as we know it as its functions are key to our survival. Blood transports oxygen and carbon dioxide around our body‚ moves nutrients‚ waste products

TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally‚ an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound‚ but also to establish its purity. To determine the melting point two
