The purpose of this experiment was to find a sufficient price to charge for galvanizing nails. In order to do this the mass of zinc coating on a typical galvanized nail needs to be known. Two different methods were used to obtain these values. Gravimetric analysis was used by measuring the mass of the nail with the zinc coating and then subtracting the mass of the nail after the zinc was dissolved in acid. Gasometric analysis was used by measuring the total hydrogen yield of the reaction. Stoichiometry

calculated using Gravimetric Analysis and to indirectly determine the percent composition of a hydrate by taking advantage of its chemical properties. Introduction: Gravimetric procedures are analytical methods in which the results are determined from the masses of starting materials and products. These methods differ from volumetric procedures in which the calculations are based on the volumes of standardized solutions used in the procedure. One of the simplest gravimetric procedures involves

be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent composition of the substance that was in the mixture. Introduction : Percent composition is about calculating the percentage of a specific

Determination of Cobalt Oxalate Hydtrate Introduction The objective of this lab is for students to determine the percentage of cobalt oxalate hydrate using the gravimetric analysis. They will also do a redox titration to determine the percentage of oxalate in the compound. After the percentages are calculated‚ you will determine the percent water by the difference of Oxalate and Cobalt from %100. Procedure Determination of Cobalt 1.

by transmitting microwaves through soil samples. A relation between output power and soil moisture is obtained by analyzing the output power data for the soil samples. The relation is verified using known values of the moisture evaluated using gravimetric analysis. Experiments were conducted in the x- band frequency range of (8-12 GHz).Further an embedded system can be developed for the in-situ measurements of soil moisture.
