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

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

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

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

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

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

One of the objectives is to separate C10H8‚ NaCl and SiO2‚ and determine their percentages in the mixture. Since the mixture

Mario Renteria Mrs. Weathers Chem 04a 27 Jan‚ 2012 Lab Report Introduction: A popular technique in separating components of a mixture is paper chromatography. We use paper chromatography to separate mixtures and isolate there components to collect them individually. In this experiment‚ we will use acid- base indicators to help determine the unknown mixture. Acid- base indicators will change in color when the presence of pHs rise and fall when acids or bases are added to a solution. After setting

5.05 Mixtures & Solutions Lab Report By Nathan Mitchell 4/23/15 Background Information & Research 1. Paper Chromatography is a method used for the separation of colors which are also referred to as colored chemicals/substances or pigments. This method is used for experiments‚ to identify coloring agents and to separate out a compound into its various components. 2. 3 real-world uses for paper chromatography include forensic testing‚ performance enhancing drug testing‚ and Ebola immunization. 3.
