tension and for hardness. One had been cold drawn and the other was normalised. The specimens were grinded using fine and coarse silicon carbide paper to give a smooth finishing before testing using a Vickers Hardness testing machine. The indenter was pressed into the specimens by an accurately controlled test force and the size of the indentation was observed by measuring the diagonals and averaging them out to get the Vickers hardness. The cold drawn specimen had a higher Vickers hardness of 285 and

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

Complexometric Determination of Water Hardness. Abstract: Using complexometric method of calculating water hardness‚ an EDTA solution was made and calculated to be around .00209M. This EDTA solution was then used to titrate a water sample with unknown hardness. The sample used was sample #18. The hardness of the sample was calculated to be 180505 ppm. This is within normal levels for the Mesa area. Introduction: This experiment focuses on titration with EDTA. Titration

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

important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. In my essay‚ I will discuss the luster‚ hardness‚ cleavage‚ fracture‚ common colors‚ distinguishing characteristics‚ uses‚ and composition of the mineral Galena. I will explain each property elaborately. Galena specimens may tarnish when exposed to air‚ becoming dull in luster
