Experiment 5 The Quantitative Determination of an Acid in Carbonated Beverages Thomas Canfield Kelly Caddell Chemistry 144B T.A. Brock Marvin 15 October 2012 Methods: Two sodas containing citric acid were investigated in this experiment. Each soda was titrated using one of the two experimental methods. These methods are the traditional titration and the modern titration. Carbonic acid was already removed from the soda by boiling it. Both of the two different titration methods

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

Water Quality and Contamination Water Quality and Contamination Introduction Abstract My lab report was based on how ground water could be affected by contaminants that surround us everyday. “ Access to safe drinking water depends not only on the quality of water at source but also on contamination throughout it’s way to the user and practices related to purification and sanitation” ( Mishra‚ S.‚ & Nandeshwar‚ S. 2013).I was very surprised that the detergent

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Influence of Heat Treatment on Hardness and Corrosion Resistance of Commercial Aluminium Mayeedul Islam 1‚*‚ S. M. Najmul Hoque2‚ M. Abdullah Al Mahmood2‚ A. A. Shisir 2 ABSTRACT Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties
