Complexometric Determination of Water Hardness 9/12/2013 Abstract: Two sets of acid-base neutralization titrations were conducted for experimental analysis. The first set of titrations was to standardize a solution manufactured in the lab. An approximate solution of Na2EDTA of 0.004 M was titrated against a known solution of 1.000 g CaCO3/L to deter mine to exact molarity of the Na2EDTA. Ca2+ + Na2EDTA → CaEDTA + 2Na+ The second set of titrations was to use the now standardized Na2EDTA

All managers need to build good working relationships with the people who can help them do their jobs. The number and breadth of people involved can be impressive—such operational networks include not only direct reports and superiors but also peers within an operational unit‚ other internal players with the power to block or support a project‚ and key outsiders such as suppliers‚ distributors‚ and customers.

Acid Determination of Vitamin C Tablets and Salt Solutions Chem 1290-016 03-05-2010 ------------------------------------------------- Purpose: The purpose of this lab was to use acid-base titrations to find the mass percent of ascorbic acid in a Vitamin C tablet. A known concentration of sodium hydroxide was used and the value found was compared to the stated amount of ascorbic acid listed on the vitamin container. Also in this lab the acidity of different salt solutions were tested using

lab is to determine the identity of an unknown liquid by measuring its density and its boiling point and try to match it with those solutions given in Table 2 of experiment 2. Procedure Part A In Part A‚ The main purpose was to find the determination of the density of the unknown (j41) and by doing that we had to determine volumes of the unknown liquid (j41) using three different volumetric devices which are graduated cylinder‚ pipette and burette. Then we had to perform three measurement
