Stir the reaction mixture for a few minutes. 10. Obtain a piece of filter paper‚ determine its mass. (Record mass) 11. Set up the apparatus (funnel‚ ring stand‚ filter paper) for filtration while the precipitate in the beaker settles. 12. Place the empty beaker under the funnel and transfer the reaction mixture to the filter paper. (Careful! Do not allow reaction mixture to rise above the rim of the filter paper) 13. Add approximately 10 mL of distilled water

structure of research article is an hour-glass symmetry the business report‚ in general‚ has the shape of a funnel. The hour-glass symmetry means that scientific report tries to identify a gap in existing research and fill it before broadening out again to make generalizations and conclusions based on the findings. This makes the scientific report more theoretical comparing to business report. The funnel shape in business report means that instead of making generalizations and conclusions the goal of business

two and filter each using a large Buchner funnel into a 500-mL filter flask. Use additional filter flasks and Buchner funnels as necessary and change the filter paper in the funnel when filtration slows due to clogging. You may need to add excess water to remove all of the spinach remnants from the blender. 3. Meanwhile‚ prepare 375 mL of petroleum ether/acetone solution in a ratio of 8:2. Pour about 300 mL of this solution into a 1000 mL separatory funnel along with an equal amount of the filtered
