Introduction Why: The goal of this experiment is to determine the water hardness of the prepared unknown water sample. Determining water hardness is a useful test that measures the quality of water for its household and industrial users. Water’s hardness arises from the presence of metal ions – specifically metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium‚

study the hardness of different types of materials‚ and to understand the significance of this property in materials. The materials and the aforesaid property have significant use in civil engineering. Hardness is defined as a measure of a material’s resistance to localised plastic deformation (i.e. small dents or scratches). As said above‚ a variety of metal alloys were used in the experiments to understand how each of these metals is characterised as a hard metal and to compare the hardness of different

Mg2+ Determination using EDTA Linh Nguyen Chem 1212L – 165 Feb 08 ‚ 2014 Purpose and Procedure: The purpose of this experiment is using Compleximetric titration and EDTA to determine the concentration of Mg2+ in solution; and also calculating the percent by mass of MgO in the unknown sample. This procedure results no significant deviations. The procedure for the experiment is from the lab manual referenced below Laboratory Experiments for Chem 1211L & 1212L (6e)

The micro-hardness test can measure the case to core depth parts. Micro-hardness testing is required where the superficial hardness test is not conceivable due to material’s small geometrical shape. The welded part we were going to examine‚ experienced the similar criteria since the welded bead of the joint was way too small. To test the hardness of our welded area we had gone through a micro-hardness test using a Shimadzu micro-vicker hardness testing machine. In the following

11 November 2014 Chem 111 Experimental Chemistry I Section 104 The Pennsylvania State University Lab Report on Experiment 10- The Chemistry of Natural Waters Introduction What is water hardness? Water is extremely important to all living things and even to non-living things‚ indirectly. Therefore‚ the way water travels and gets to a place is also extremely important because its transportation methods determine the chemicals that get involved and added into the water as it travels. This relates

Determination of Chlorine and Iodine in Water I. Introduction The purpose of this laboratory was to determine the amount of chlorine and iodine in a sample of water by titration using a starch indicator and to standardize a sodium thiosulfate solution. Chlorine is added to municipal water supplies to purify it enough to become safe to drink. Iodine is also added to water when people camp or go hiking in the back country where they cannot bring purified water along. Chlorine and iodine are
