Synthesis and gravimetric analysis of cobalt oxalate hydrate target grades: 10 - 14 accommodates 24 students working in groups of 2 students will enjoy this lab as they experience multiple techniques required for ap chemistry synthesizing cobalt oxalate hydrate by precipitation, gravimetric analysis by dehydration, and oxidation-reduction (redox) titration on a unique compound.
Lab report cobalt oxalate hydrate 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.
Coc2o4 2h2o +2 is the most common oxiidation state, so i simply looked up cobalt(ii) oxalate and found that it is a dihydrate +3 oxidation state is also common however, when looking it up, you cannot locate the existence of a hydrate there is nothing in the balanced equation that gives you.
Determination of the composition of cobalt oxalate hydrate experiment 12 robbie kinsey partner: debnil chowdhury chem 1312-d ta’s: russell dondero & sylvester mosley february 9, 2000 purpose the purpose of this lab was to determine the percent cobalt and oxalate by mass, and with that information, the empirical formula for cobalt oxalate hydrate, using the general formula coa(c2o4)bch2o. Chem 1211 & 1212 lab - dr kim's section georgia perimeter college - dunwoody campus link to gpc dunwoody chemistry lab home site for general information the lab home site above has useful information such as actual pictures (taken by our lab staffs) of experimental set-up/progress/results in color.
James, 1 introduction: in this experiment, we performed on hydrated compounds and were able to measure specific masses in a quick, but accurate manner we began by creating a compound, which will be used later to test/analyze for cobalt, oxalate and water content in experiment 3 after analyzing the compound and finding the amount of moles of each content, we will then be able to calculate.
(determination of the composition of cobalt oxalate hydrate) special equipment analytical balance sodium oxalate, in your report, you will describe the procedures you will need the solutions and the crucibles when you perform exp 12 (determination of the composition of cobalt oxalate hydrate) procedure. Making lab and production operations more efficient and competitive offering a wide range of support and services lending expertise to improve quality and boost scientific productivity helping achieve innovation faster home cobalt (ii) oxalate dihydrate cobalt(ii).
