Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent

In this lab‚ the pH of flat sprite and a fresh sprite are compared two ways: one way was to record the pH directly with a digital pH probe and the other was to calculate the concentration through titration. Because the reaction is a neutralization reaction‚ the concentration of can be calculated if the concentration of is known. At the end of the titration‚ the moles of will equal the moles of and the pH is expected to be greater than 7 because the found in sprite is weak and is a strong

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration
