Separations of the Components of a Mixture January 9‚ 2013 Hailey Rounds Partners: Kelsy Shay Katie Nelson Objectives: The purposes of this experiment are to separate two components in a mixture‚ specifically sodium chloride and silica‚ and find the correlating percent composition of each. Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to

in Ms. O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture‚ then the vegetable oil will float and the water will sink”. This is the important information

Experiment 3Quantitative Separation of Mixtures This experiment performs the quantitative separation of thecomponents of a mixture. A mixture is the mixing of two or more substancestogether. The proportions of the components in the mixture can be varied.And the resulting mixture can be either homogeneous or heterogeneous‚depending on the properties of components such as solubility.In this experiment‚ you are going to separate a water-solublecomponent from water-insoluble components

Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

The separation scheme was created by centrifuging a controlled sample of one of the ions or anions combined with one of the reagents such as NaCl. It was found that it could be separated out after centrifuging and would result in a sample without the ions or anions if it precipitated. With the data from week one a method of adding the reagents in a certain order would result in the ability to separate all ions or anions out of a solution. Overall‚ knowing how the cations or anions reacted with certain

calculations. Analysis/ Critical Thinking Questions: Compare your data for the pure substances with the data for each of the two solid mixtures. Which of the pure substances shows behavior that is similar to what you saw with the the two-solid mixtures (Mixture 1 and Mixture 2)? If you cannot positively identify your mixture‚ discuss the possibilities for the mixture. The starch and mixture 2 are both similar because they both did not penetrate when the vinegar was added; when the water was added the laid on

evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures‚ it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture‚ another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials

Purpose: Unknown mixtures will be separated by means of chromatography in which the mixture will be passed in a solution through a medium leaving behind components of the mixture at different rates‚ therefore‚ different spots on the absorbing substance. This will help determine the identity of unknown mixtures. The spot colors on the strip of filter paper and the Rf values of the unknown samples will be compared to those of known samples. To find the position of the spots on the strip of paper‚ we

Purpose: In this lab‚ a mixture of naphthalene (C10H8)‚ common table salt (NaCl)‚ and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance
