Set up a ring stand with distillation apparatus.
2. Start boiling.  Record the temperature every minute.
3. When the first plateau starts to end, switch the collecting tube with an empty one.
4. When the second plateau begins, switch the tube with another empty one.
5. Once finished, discard the second tube's contents.  Test the first and third fractions.]]> 2019-11-13 14:29:53 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/410580640 Micro-Melting Point zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/410588152 At least 1/2 cm of powder is required.]]> 2019-11-13 14:38:45 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/410588152 Freezing Point zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/410588369 2019-11-13 14:39:01 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/410588369 Solubility zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/410588447 2019-11-13 14:39:07 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/410588447 Procedure: zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/410588760 1. Mass the evaporating dish before pouring the solution in.
1. Set up a ring stand with an evaporating dish.  The solution should be inside the dish.
2. Start boiling.  Check through the looking glass to see if all the solvent evaporated.
3. Once all the solvent is gone, mass the remaining solute in the evaporating dish. Calculate the mass of the solvent.]]> 2019-11-13 14:39:31 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/410588760 Plastics zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/411181212 You don't have to do every test to identify all the plastics.]]> 2019-11-14 14:02:46 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/411181212 Less is Faster zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/411182744 This applies to substances AND information.]]> 2019-11-14 14:05:05 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/411182744 Go above and beyond! zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/411184147 Hit the minimum, but don't stop there.  Impress yourself by making your Padlet more personalized.]]> 2019-11-14 14:06:51 UTC https://padlet.com/zarobin671/marwbvs1t47o/wish/411184147 Procedure: zarobin671 https://padlet.com/zarobin671/marwbvs1t47o/wish/411184965 1.
