Unit Project Documenting the Scientific Method Separating Mixtures Project Separating Mixtures: How can you separate salt water to make pure and drinkable fresh water? Design and build a device to separate a mixture of salt water into its components. For example‚ what device could you build to get the most drinkable water from salt water if you were on a stranded island in the middle of the ocean? Gather data on the amount of water collected and the purity of the water‚ which can

methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid‚ methyl orange‚ a common acid/base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating mixtures of compounds‚ taking advantage of the affinity differences of compounds to separate them

The industrial separation process that I have decided to do is gold separation. Gold separation can be done in a number of ways but there is not always one way to do it‚ but the combination of a couple of these processes to extract pure gold. Gold is obtained form the lithosphere. It is separated from the ore found in the lithosphere. Gold’s symbol is Au. Its atomic number is 79 and has an atomic mass of 196.96655 amu. Its melting point is 1064.43°C‚ while its boiling point is 2807.0 °C. It is

PYROLYSIS OF SOLID WASTE ABHISHEK BARMAN(1RV11CS004) ABHILASHA (1RV11CS003) INTRODUCTION Pyrolysis is a thermo chemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). It involves the simultaneous change of chemical composition and physical phase‚ and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating". Pyrolysis is a type of thermolysis‚ and is most commonly observed in organic materials

Students at NFV middle school are on a journey to figure out a mystery mixture. They have to search through 9 chemicals to figure out which one is it. Seems easy huh? Nope‚ they have to analyze the physical and chemical properties (a very important part in this)‚ the data‚ argue‚ and give important statements on what they think is in the mix. That’s when arguing comes in‚ not arguing on the person but the statement. I think it is citric acid and baking soda. Eighth graders have to find out what a mystery

Bile is a greenish-brown liquid produced in the liver then stored in the gallbladder which is use to digest fat. Bile contains water‚ cholesterol‚ fat‚ bile salts‚ proteins and a waste product call bilirubin. If the bile has too much cholesterol ‚ bile salt‚ or bilirubin‚ they hardens into stones. There

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those
