Yuen Investigation 21: How Much Copper Is in the Coin? RC Bauer‚ JP Birk‚ DJ Sawyer We calibrated three different molarities of copper (II) nitrate. We tested for the %Transmittance of 1M‚ 0.1M‚ and 0.01M and plotted the data collected on a calibration curve based on concentration and absorbance. We used nitric acid to dissolve a penny to produce another copper (II) nitrate to test its %Transmittance and plot that on the graph to discover the concentration of that substance which came out to be

Lab 1: Calibration of Pipettes and Burettes Names TA Name‚ Thursday Lab: 1:40 P.M. - 4:10 P.M. Aim: This experiment sought to gather data regarding water volume gathered in glassware‚ then to statistically analyze the data‚ focusing on average and standard deviation‚ along with relative error gleaned from linear regression. Introduction: This experiment was divided into two parts. For part one of the experiment‚ 25 mL were transferred from a glass pipette to a tarred beaker and weighed

Hello all‚ I went into the lab and none of the Ps had notes of calibrations occurring during or between any of the task. P 24‚ 54 and 71 all have massive decreases from baseline to both task. The real problem is that with out a note of when calibration occurred there are three logical explanation for this. First‚ that they ran across campus and were not actually at baseline when baseline measures where taken thus leading to the decrease when they do finally calm down. Secondly‚ the machine could

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Belardo‚ Pia Jobelle J. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas España‚ Manila February 27‚ 2013 Abstract The analyte used is the soda ash which is titrated with an HCl titrant‚ standardized by Na2CO3. The indicators used are phenolphthalein for basicity and methyl orange for acidity. The two volumes of the titrant are then used to calculate percent composition of

Copper Sulphate Calibration Aim The objective of this experiment is to determine the unknown concentrations of solutions. Introduction With the use of absorption of light a spectrophotometer sends UV wavelengths through solutions to determine their concentrations. The light absorbed is measured as the atoms‚ molecules and ions absorb the wavelengths of light that the spectrophotometer gives off (Meah‚2013). The level of light transmitted defines the amount of light absorbed‚ for instance‚ the lower

Introduction Titration is a volumetric analysis technique used to find the concentration of an unknown substance. There are several types of titration but the one used for this experiment is called acid-base titration as the substance we are titrating is acidic. Acid-base titrations are based on the neutralisation reaction between the analyte and the acidic or basic titrant. The analyte is the solution of unknown concentration and the titrant is the solution of accurately known concentration used

Calibration of Total Station As there is height transfer from Wong Yi Chau to Tai Tau Chau‚ reciprocal leveling is needed to minimize the effect of the atmosphere as well as the line of sight and curvature corrections. As a result‚ total station will be calibrated before performing reciprocal leveling. Line-of-sight error and V-Index are determined through calibration. Line-of-sight error and V-Index The line-of-sight error or collimation error (C) is the deviation from the perpendicular between
