Theory: Distillation is the conversion of a mixture of substance into vapors which is afterwards condensed to the liquid form. It cans separation or purification of substances by taking advantage of differences in volatility. The purpose of this lab is comparing the efficiency of two distillation methods with the mixture of ethanol and 1-butanol. in theory the fractional distillation should be more efficient because of the steel sponge. The sponge acted as surface area for gas to condense on. This

Title: Separation of Mixture of Solids - Experiment 3 Date: 9/21/13 Purpose: This experiment is designed to show the different ways to separate solid mixtures into individual elements. It will also determine whether a substance can be considered “pure” or not‚ as well as determining the solubility of each mixture in water. Procedure: 1) Weigh the amount of the mixture on the digital scale. Separate the Iron out by using a magnet to filter out the Iron element. 2) Take the remaining mixture

Why Is Calcium Chloride Powder Used Extensively As A Bleaching Agent? In simple terms‚ calcium chloride is an inorganic compound having chemical formula CaCl2 (H2O)x where x can be 0‚1‚2‚4 and 6. All the salts produced by calcium chloride powder has a unique characteristic that they are highly soluble in water. This helps in applications where you need to remove snow‚ ice‚ or frost from any surface or even simple dust removal. It can absorb moisture from the surrounding environment‚ which is also

SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken‚ and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next‚ find the mass of the 250mL beaker‚ zero out the scale

MIXTURES‚ SOLUTIONS‚ SUSPENSIONS AND COLLOIDS MIXTURES A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures. SOLUTIONS A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even

Every step in this experiment has reasons behind its application. One determines the masses of the crucible and barium chloride hydrate for obvious data collection and calculation purposed. The heating of the sample slowly for 10 minutes is done to remove the water from the sample. A constant mass for the sample must be obtained so therefore it must be done slowly because if not you may loose mass from the sample. At the point where the crystalline solid changes to a powdery solid the sample must

ISE: The Determination of Chloride Unknown: #34 I. Purpose: In experiment V‚ “ISE: The Determination of Chloride”‚ the concentration of an Unknown Chloride solution‚ and the Wt% of NaCl in a sample of celery salt‚ were both determined. To determine the concentration of an Unknown Chloride solution‚ a Calibration plot is first prepared. The Calibration plot is made by first measuring a series of known concentrations of Cl- (with the same activity of the unknown solution) and obtaining

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

Mixture separation Lab I am one of the chemists assigned to design a cost effective procedure for handling the CARBOSE separation and recovery and hazardous waste disposal. The difficulties were trying to figure out is how we can effectively separate Carbose‚ sand‚ and naphthalene? The hypothesis we chose to solve this problem was if we put the mixture into water‚ alcohol‚ and mineral spirts‚ then in each solution one or more substance will not dissolve‚ will be visible‚ and also able to separate

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
