Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex

English 201 28 September 2012 Work Hard; Play Hard Work hard. Play hard. Two completely different things but they should coincide. So many people these days get by with the smallest amount of effort‚ and so many people play too much. An equal balance of the two makes for a high-quality pleasurable life. The harder you work the more you deserve to play‚ and trust me; you’ll feel better about it. Hard workers in this day and age can sometimes be very hard to come around. There are so many younger

Determination of Water Hardness Using a Titrator Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains high

Soft power without hard power is no power. In the early 1990s‚ Joseph Nye’s book Bound to Lead: The Changing Nature Of American Power ignited a huge discussion among society of the need to transition from America’s traditional use of hard power to something more benign which he termed soft power. Before looking at the two branches of power‚ we first define power as the ability to do something or act in a certain way. As Nye had pointed out‚ nations can wield power in two forms‚ soft and hard power

Joel Feinberg says that hard paternalism has all the characteristics of soft paternalism‚ and the point where it differs is when the consent of the subject ceases to have any significance. Where soft paternalism would say that the State must control only ‘impaired’ choices‚ hard paternalism would eliminate the question of choice. For Hard Paternalism to be exercised‚ roughly four requisites must be satisfied. Firstly‚ the paternalism

The objective of this lab is to determine the hardness of water‚ using the data collected from each titration performed with the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the indicator Eriochrome Black T to determine the concentration of M 2+ ( Mg 2+ or Ca 2+) metal ion impurities. Chemical principle or theory involved in this lab: To determine waters hardness we will use a technique called a chelometric titration
