Add sulfuric acid to the mixture of benzoic and methanol‚ heat up the mixture to 65 oC. Transfer the mixture to the separatory funnel and add ether‚ sodium bicarbonate and saturated sodium chloride-brine solution‚ drain the bottom layer each time and remain ether layer. Decant the solution with calcium chloride‚then evaporate the ether by steam bath and cool down. The product is methyl benzoate. Pour methyl benzoate into cool concentrated sulfuric acid and keep the temperature below 10oC. Add concentrated

Calcium hypochlorite is a chemical compound with formula Ca(ClO)2. It is widely used for water treatment and as a bleaching agent. This chemical is considered to be relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). Preparation It is manufactured by the calcium process: ~\mathrm{2Cl_2 + 2Ca(OH)_2\longrightarrow \ Ca(OCl)_2 + CaCl_2 + 2H_2O}. "Bleaching powder" is a mixture of calcium hypochlorite (Ca(OCl)2) and the basic chloride CaCl2‚ H2O with

fluids is essential to their performance. In this laboratory exercise the aim is to test three drilling fluid samples for; density and rheological properties‚ Fluid loss‚ chemical analysis i.e. testing pH‚ alkalinity‚ testing for chloride ions‚ calcium carbonate‚ calcium‚ bentonite; also determining the amount of solids present in the samples as well as volumes of oil‚ water and solids contained in the sample‚ and to test for contaminates such as NaCl and KCl. These tests helps us to determine the

Water Testing Lab Conclusion In this lab‚ chemical tests were used to check for the presence of calcium‚ chloride‚ and sulfate ions in water samples. To do this‚ the testers started with five samples: a reference‚ a sample of only the chemical being tested for‚ a control‚ distilled water‚ two home water samples‚ and a school water sample. To test for the ions in the water‚ a chemical that would react with the ion and create a precipitate was added. If the precipitate was not easily visible‚ a

Chlorine is soluble unless it is bonded with silver‚ lead‚ or mercury‚ so this led the precipitate formed to definitively contain either lead chloride or silver chloride. The formation of a precipitate (either AgCl or PbCl2) was expected‚ which allowed the remaining liquid‚ containing either barium chloride or calcium chloride‚ to be separated and set aside into another test tube to be tested in Part B. The precipitate could then be further tested by mixing in potassium chromate to
