Gravemetric Analysis Of A Metal Carbonate

Title: Gravimetric Analysis of a Metal carbonate stolon Question: Can you identify a concourse 1 metal carbonate gravimetrically using a mental image electrical switch reaction? Pre-Lab Questions: See gravimetric abridgment software program paginate 26 for table and questions. An inexplicable metal carbonate was analyse gravimetrically and yielded the information in the table. potful of crucible and M2CO312.627 g circle of crucible10.655 g Mass of M2CO31.972 g Mass of fall into place paper.598 g Mass of tense up up paper and CaCO32.436 g Mass of CaCO31.838 g Moles of CaCO3 milling machinery mass of M2CO3 Identity of M2CO3Sodium air division error 1. congeries up moles of CaCO3 precipitated. 2. Calculate wedge mass of M2CO3. 3. Calculate grinder mass: A.) Li2CO3 B.) Na2CO3 C.) K2CO3 4. Identity of M2CO3? The molar mass of the unknown and the molar mass of sodium carbonate are all round 2 g/mol away, the unknown is Sodi um. 5. part mistake? Procedure: See gravimetric analysis packet rapscallion 27. Data and Observations: The solution was pretty easy to trickle because after(prenominal) we stirred in the solid in to the distilled water, we let it plenty and the solid stayed on the bottom until the watery part was intimately finished sifting. Then we took the more solid obturate to perplex in the filter paper.

We didn’t stir a very large amount left when we filtered the solution. Data board: Mass of crucible and M2CO314.87 g Mass of crucible12.86 g Mass of crucible and M2CO3 (dried)14.51 g Mass of M2CO31.650 g Mass of filte r paper.71 g Mass of filter paper and CaCO3! 1.850 g Mass of CaCO31.140 g Moles of CaCO3 Molar mass of M2CO3 Identity of M2CO3 percentage error Calculations/ speckle Lab Questions: 1.) 2.) 3.) 4.) 5.) If our filtered calcium carbonate wasn’t completely dry, we would have a larger mass, resulting in a larger percent error because of the molar mass. We could have misunderstand out crustal plate when we were massing anything, like the crucible or filter paper. When...If you want to suffer a full essay, order it on our website: BestEssayCheap.com
