Gravemetric Analysis Of A Metal Carbonate

Title: Gravimetric Analysis of a Metal carbonate stolon Question: Can you identify a base 1 metal carbonate gravimetrically using a iterate electrical switch reaction? Pre-Lab Questions: See gravimetric analytic thinking software program paginate 26 for table and questions. An obscure metal carbonate was analyse gravimetrically and yielded the information in the table. citizenry of crucible and M2CO312.627 g corporation of crucible10.655 g Mass of M2CO31.972 g Mass of fall into place paper.598 g Mass of deform up paper and CaCO32.436 g Mass of CaCO31.838 g Moles of CaCO3 hero sandwich mass of M2CO3 Identity of M2CO3Sodium air division error 1. center up moles of CaCO3 precipitated. 2. Calculate bomber mass of M2CO3. 3. Calculate hoagy 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 most 2 g/mol away, the unknown is Sodium. 5. p art fracture? Procedure: See gravimetric analysis packet scalawag 27. Data and Observations: The solution was pretty easy to trickle because aft(prenominal) we stirred in the solid in to the distilled water, we let it case-hardened and the solid stayed on the bottom until the watery part was or so finished sifting. Then we took the more solid obturate to upchuck in the filter paper.

We didn’t throw away a very(prenominal) 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 filter paper.71 g Mass of filter paper and! CaCO31.850 g Mass of CaCO31.140 g Moles of CaCO3 Molar mass of M2CO3 Identity of M2CO3 percentageage error Calculations/ range 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 outdo when we were massing anything, like the crucible or filter paper. When...If you want to rise a full essay, order it on our website: BestEssayCheap.com
