Willy Rupprecht Date(s) performed: October 2 - 3‚ 2012 Gravimetric Analysis of an Unknown Group 1 Metal Carbonate Purpose: The purpose of this lab is to determine the identity of a Group 1 metal carbonate compound by gravimetric analysis. Procedure: The unknown carbonate is weighed and then dissolved in water. A solution of CaCl2 (calcium chloride) is added to the metal carbonate solution to precipitate the carbonate ions as CaCO3 (calcium carbonate). The precipitate is then filtered‚ dried

Introduction of Lab 5: Analysis of a Zinc: Aluminum Alloy The analysis of a metal alloy was designed to learn how to use the Ideal Gas Law (formulas listed below) in a laboratory setting in relevance to acquiring moles of gas created‚ thus giving us one step closer to finding the molar mass. The importance of the Ideal Gas Law‚ as well as the other gas laws‚ is that it signifies the relationship between the properties of an ideal gas. These properties assist in the explanation of the Kinetic Molecular

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

Zinc and Hydrochloric-Acid Written By Kahlil Zione Date:02/02/05 Abstract: We observed the reaction between zinc and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is effected by the amounts of both substances added to the solution. Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric

Mass of Zinc Determination on Galvanized Nails Introduction. In this experiment the mass of zinc on galvanized iron nails was calculated to determine the appropriate price that should be charged to coat a nail with zinc (galvanize) it. The effectiveness of gasometric and gravimetric analysis were assessed by carrying out both methods mathematically using values determined by this experiment‚ and then comparing these values using their percent differences. The mass of zinc found on each nail can

Abstract: Gravimetric analysis can be used to determine the percentage of phosphorus in plant food. A precipitant of known composition is produced and weighed to find percent of phosphorus in compound. From the mass and known composition of the precipitate‚ the amount of original ion can be determined. Introduction: Gravimetric analysis is based on the measurement of mass. Gravimetric analysis involves isolation of an ion in solution by a precipitation reaction‚ filtering‚ washing the precipitate
