Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

Title: Reaction of Iodoethane with Sodium Saccharin- Ambient Nucleophile Dates Performed: February 21 + 28‚ 2013 Date Submitted: March 14‚ 2013 Abstract: The product ratio of N-ethylsaccharin to O-ethylsaccharin that occurred due to alkylation with iodoethane at 80 oC was determined to be 81.5% to 18.5%‚ respectively‚ based on an analysis of the 1H NMR spectrum that was collected. The melting point range of 87.8-94.7 oC also indicated that the mixture was largely composed of N-ethylsaccharin

Membrane process can be used to separate chemical substances in various types and sizes from microscopic to molecular level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be useful in separating neutral‚ basic‚ and acidic organic substances by controlling the pH of the aqueous layer

remains frozen. When the temperature reaches 0°C (the melting point of water)‚ the ice begins to melt. Because melting is an endothermic process‚ the heat we add at 0°C is used to convert ice to water and the temperature remains constant until all the ice has melted. Once we reach this point‚ any further addition of heat causes the temperature of the liquid water to increase. You observed a phase change process for ice (solid water) being melted‚ heated and then boiled in class. A graph of the temperature

Abstract The chloride present in an unknown soluble sample was precipitated into silver chloride through precipitation gravimetry. The colloidal silver chloride originally formed was converted to a crystalline solid by controlling certain parameters of the experiment such as temperature‚ pH of the solution‚ and concentration of AgNO3. Once the solid was large enough‚ it could be washed‚ filtered‚ and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %.

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

Sodium hypochlorite‚ also known as chlorine bleach‚ soda bleach‚ or household bleach is a chemical with the formula NaClO. A common way sodium hypochlorite gets into the San Francisco bay is through daily household cleaning products such as laundry bleach. In a survey conducted by The Clorox Company‚ it was found that four out of five households use sodium hypochlorite bleach for their laundry. Since laundry detergent companies are not required to list every ingredient‚ customers are often not aware
