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

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Lab Report: Hard Water Purpose: The purpose of this lab is to determine whether a liquid is hard water or not. Background: Hard water is the water that has a high amount of mineral in it‚ usually Ca2+ and Mg+. These cations enter the source of water by leaching from minerals within a wet underground layer of water- bearing rock‚ or an aquifer. According to the WHO‚ hard water is not harmful to human’s health but it’s a serious problem in the water industry. Household plumbing and appliances

MULTIPLE-TUBE FERMENTATION TECHNIQUE FOR MEMBERS OF THE COLIFORM GROUP* 9221 A. Introduction The coliform group consists of several genera of bacteria belonging to the family Enterobacteriaceae. The historical definition of this group has been based on the method used for detection (lactose fermentation) rather than on the tenets of systematic bacteriology. Accordingly‚ when the fermentation technique is used‚ this group is defined as all facultative anaerobic‚ gram-negative‚ non-spore-forming

Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen and Oxygen. This HHO GAS is then sucked into your engine and mixed along with the air from

Water quality and contamination Tijuana R Harvey SCI207 Dependence of Man on the Environment Instructor: Kathryn Garland Nov.3‚ 2014 Water Quality and Contaminants Water being one of our most precious resources we have to question the quality of our water quality and things that maybe contaminating it. Water affects not only humans it affects other living things such as animals‚ plants‚ and aquatic life and hydroelectric machinery. Some would believe that it should be a human right to have clean

Intelligent Water Pump for Farmer Now days in most of the villages due to ‘Load shading’ there is irregular electricity supply to water pump. In most of the cases the water pumps are 2 to 3 km away from the farm. Due to electricity failure a farmer must to go every time near to pump controller to turn ON/OFF the pump. This problem becomes most serious during night time. Also delay in the process of water pump switching causes wastage of electricity‚ water as well as time. Objective: The

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Condensation and evaporation are represented in the model. Condensation formed inside the jar and under the lid and the warm water evaporated. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Precipitation and infiltration did not get represented
