Purpose: To prepare isopentyl acetate from isopentyl alcohol and acetic acid by the Fischer esterification reaction. Materials: West condenser‚ 250 mL round bottomed flask‚ two 250 mL flasks‚ heating mantle‚ boiling chips‚ graduated cylinder‚ sodium bicarbonate‚ isopentyl alcohol‚ glacial acetic acid‚ concentrated sulfuric acid‚ separatory funnel Procedure: 1. Place 50 mL of isopentyl alcohol in a 250 mL round bottom flask and add 60 mL of glacial acetic acid. Add the acid very slowly. 2.

exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited reactants. It is hypothesized that the limited reactant of this experiment is the baking soda. Materials- * 2 beakers * Sodium bicarbonate * Vinegar * Beral Pipette Procedure- 1) Label the beakers A and B. 2) Weigh the beakers to two decimal places. 3) In Beaker A‚ place approximately .5- .75 g of baking soda. 4) Weigh Beaker A with the powder to two decimal

Neutralize any spilled HCl with sodium bicarbonate (baking soda) and wipe up immediately. Gasses will be released when sodium bicarbonate is added to your separatory funnel. Do not stopper funnel after the addition of sodium bicarbonate solution. Vent separatory funnel frequently while shaking. Do not vent sep funnel toward another person or yourself. Liquids may spray out while

Amanda Ayers 09/07/2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well

4 Tips to Get Rid of Dirty & Grimy Tile Grout Scrubbing and mopping your tile floors aren’t enough to clean up dirty and grimy grout. There are certain things you must consider in figuring out which cleaning method can renew your floor’s surface‚ which includes the type of tile you have and the grout colour. Whether you have it cleaned professionally or handle the job yourself‚ following these reminders can certainly save your floor. Warm Water Pair a stiff-bristled brush with water and begin

Laboratory Report Title: Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules

Developing a Model Airbag Lucy Peng Methods: To begin the experiment‚ my partner and I brainstormed several different airbag model designs: the first model containing a barrier of some sort to separate the NaHCO3 and the CH3COOH (Model 1) and the second model containing a “cup” or “pocket” taped to the wall of the plastic bag that would prevent the reactants form coming into contact (Model 2). We then measured arbitrary amounts of NaHCO3 using plastic weighing boats and an electronic scale.

Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these

the plant.  The CO2 levels: Increased CO2 levels also increase the rate of photosynthesis. The variable I am going to investigate is the level of CO2‚ however‚ the addition of NaHCO3 (sodium bicarbonate) to the water may affect the osmotic ability of the water. Just 2g of sodium bicarbonate in 1000ml of water gives the equivalent salinity of seawater‚ and as Elodea is a fresh water plant‚ it cannot survive in salt water. I will need to take this into account when measuring the NaHCO3
