Experiment 05 Water Hardness October 8th‚ 2013 The hardness of water was determined using the methods of titration‚ conductivity‚ and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present

thank god for keeping me calm with all the stress I had. Abstract The purpose of my project is to explain the processes of the water cycle‚ explain what it is‚ and to show the process of evaporation and what happens during this process.my procedure consist of placing the small container in the middle of the large ‚ clear bowl. Fill the bowl with a little water‚ being careful not to fill the small container inside. Cover the bowl with plastic wrap‚ and fasten the plastic wrap around the rim

Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken

The water cycle is also known as the hydrologic cycle. The water cycle describes the movement of water on‚ above and below the surface of Earth. Water can change states through the stages of the water cycle. Water can change from a solid to a liquid to water vapor in various places of the water cycle. Water moves from one lake to another‚ just like from an ocean to the atmosphere. Water travels by different processes of evaporation‚ condensation‚ precipitation‚ infiltration‚ runoff and subsurface

70% water and 30% of land. Our body is also composed of 2/3 of water. In other words life without water is INPOSIBLE.Imagine what would happen if amount of water in nature would be drastically reduced? I believe we all know the answer and the consequences. The entire flora‚ fauna and the entire human being will die slowly. Now a day‚ we have a lot of amount of water in our planet but that is a big paradox because a big part from that water is polluted. Basically living the life without water or with

WATER CONSERVATION INTRODUCTION: Water is essential for life on earth. Water is needed for growing food‚ keeping ourselves clean‚ generating power‚ controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation – Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation

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
