Complexometric Determination of Water Hardness By Nick Williams CHM 152 Lab dates: Aug 28th 2013 Dr. Weide Abstract: When a polyatomic ligand with multiple lone pairs of electrons available for bonding to a central metal ion forms a complex with a metal ion‚ a process known as chelation takes place. Metal ion impurities can be found by using disodium salt of EDTA to determine the concentration of M2+ by complexometric or chelometric titration. Erichrome Black T makes it easy to see

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab‚ the variables in the ideal gas law are known or can be found aside from the constant R. Thus‚ the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction: Mg (s) + 2HCl2 (aq) H2 (g) Procedure: 1. Ribbons of magnesium (5) were cut to the approximate

can reduce their risks. Instead of foods that are good for them‚ people often eat hamburgers‚ cheese‚ French fries‚ and pizza. These common foods contain large amounts of saturated fat‚ which is the worst kind of fat. Though light and fat-free products are constantly being introduced to the consumer market‚ many people still buy food that contains fat because it often tastes better. However‚ eating fatty food can increase a person’s chances for some kinds of cancer. People do not eat as many fresh
