6. A sample of an alum was analysed by atomic spectroscopy and gravimetrically to determine its structure. A 0.1000 g of the sample when treated with BaCl₂ produced 0.0984 g of a white solid after drying to constant weight. Another 0.1000 g sample of the alum when heated at 105°C for several hours produced a weight loss of 0.04558 g while the % of K in the sample was determined by atomic spectroscopy to be 8.240%. Use these results to work out a formula for the alum. [M,/ g mole¹: K 39.10; Al 26.98; BaSO, 233.39; SO² 96.06; H₂O 18.0148]

I extracted caffeine by using chloroform and magnesium sulfate to dehydrate the organic phase. I got crude caffeine just by solvent evaporation at room temperature. However, I wanted to conduct Raman spectroscopy measurements but I did not get the characteristic peaks. I think that it has to be whit chloroform presence. So I let the crude caffeine 24h at 65 degrees but still I did not get any peak. What can I use to rinse my crude caffeine extract to remove all chloroform molecules? Or what is wrong with my extraction?
