Experiment 1: Calibration of Volumetric Glassware Introduction: Volumetric glassware is used to accurately measure volumes. Despite all of the tools and instruments available for the use of measuring values of various data‚ it is impossible to measure the true value of anything. This experiment is intended to develop a person’s capacity to handle volumetric glassware. One must understand how to handle volumetric glassware to acquire the best possible data from the equipment used in lab. Although

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

use to determine the percent composition is Gravimetric. With this method we use the mass of the reactant and the mass of the product. Another way to acquire the percent composition is by the Volumetric Method. This method requires measuring the water displaced by the O2 gas. If the experiment is done correctly‚ we should be able to calculate the percent composition of KClO3 by using both methods. Theory: This experiment requires us to use both the Gravimetric and Volumetric methods in order to

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce
