Gravemetric Analysis Of A Metal Carbonate

Title: Gravimetric Analysis of a Metal carbonate stolon Question: Can you identify a assort 1 metal carbonate gravimetrically using a duplicate electrical switch reaction? Pre-Lab Questions: See gravimetric depth psychology software program paginate 26 for table and questions. An hidden metal carbonate was analyse gravimetrically and yielded the information in the table. big money of melting pot and M2CO312.627 g band of crucible10.655 g Mass of M2CO31.972 g Mass of fall into place paper.598 g Mass of filter 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. ticker up moles of CaCO3 precipitated. 2. Calculate grinder(a) mass of M2CO3. 3. Calculate molar 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 active 2 g/mol away, the unknown is Sodium. 5. part fallacy? Procedure: See gravimetric analysis packet scalawag 27. Data and Observations: The solution was pretty easy to trickle because after we stirred in the solid in to the distilled water, we let it peck and the solid stayed on the bottom until the watery part was most finished sifting. Then we took the more solid obturate to rank in the filter paper.

We didn’t bind a in truth 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 partage error Calculations/ jeopardize 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 outperform when we were massing anything, like the crucible or filter paper. When...If you want to flap a full essay, order it on our website: BestEssayCheap.com
