    Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

    Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

    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
