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

In answering the question this report will outline the causes of social inequality and show that Social Inequality is prevalent in all societies including Jamaica. Race & Ethnicity Within sociology‚ the term ethnic‚ race‚ minority‚ and dominant group have very specific meanings‚ different from the meanings the terms have in common‚ their usage. These concepts are important in the development of a sociological

and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to clean the probe and

How do the unique chemical and physical properties of water make life on earth possible? Heat Capacity the amount of energy required to raise the temperature of something one degree celcius Cohesive strength - The internal strength of the adhesive. The measure of a label’s resistance to removal. Surface Tension - the attraction of molecules to each other on a liquid’s surface‚ creating a barrier between the air and the liquid.

how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

Title: Colligative Properties & Osmotic Pressure Background: Important terms to study from this lab assignment are colligative properties‚ membrane permeability and osmotic pressure. First‚ colligative properties are “those of a solution that depend solely on the number of solute particles present‚ not the identity of those solute particles. These properties include: vapor pressure lowering‚ boiling point elevation‚ freezing point depression‚ and osmotic pressure” (p. 17 lab manual). In this experiment

Topic 6 Water Quality and Water Management What determines water quality? Drinking water should be colorless‚ odorless and flavorless; this means that there are no organisms and sediments in the water‚ but it does not mean that if your drinking water look‚ smells and taste clean‚ that does not mean that there is nothing else it. Water also contains dissolved solids: •Sulfur •Calcium •Magnesium If water contains a lot of dissolved calcium and magnesium it is called hard water
