Water Analysis Lab Report Purpose: In this lab we will be testing a number of water samples. These water samples come from various water sources. Each of these water samples will undergo four different tests. The four tests include a pH test‚ a conductivity test‚ a total and phenolphthalein and alkalinity test‚ and a total hardness test. This lab requires comprehension of lab material and techniques learned in prior labs (Kippenhan‚ 2012). Procedure: Each

Percent Water in a Hydrate PURPOSE To determine the percent water in a hydrate sample. INTRODUCTION Many substances contain water molecules as a part of their crystal structure. We call such solids hydrates‚ and we call the bound water the water of hydration. A hydrate has a definite number of water molecules bound to each anhydrous salt unit. The formula of the hydrate copper(II) sulfate pentahydrate is CuSO4 · 5 H2O The dot indicates that the molecules of water are attached to the ions in

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
