Why should we acidify the sodium carbonate extract?
Acidifying the sodium carbonate extract helps to convert any remaining phenol into the non-polar phenol form, which is more easily extracted with an organic solvent. This step also helps to separate the phenol from other compounds in the mixture, making it easier to purify and isolate the phenol. Additionally, acidification can help to adjust the pH of the solution to a range that is more suitable for subsequent reactions or analyses.
How do you extract gold?
Gold is typically extracted from ores using a combination of techniques such as crushing, grinding, and chemical processes like cyanidation. The ore is pulverized to release the gold particles, which are then leached using cyanide to dissolve the gold into a solution. This solution is then processed to recover the gold through techniques such as carbon adsorption or precipitation.
Why can iron be used to extract copper?
Iron is a more reactive metal than copper, and so will replace it in a compound. The more reactive a metal is, the more stable it is in a compound, and the less stable it is in its elemental form. So relative to one another, iron is more stable in a compound while copper is more stable as apure element.
Why is fluorine not detected in sodium extract with agno3 solution?
Fluorine is not detected in a sodium extract with AgNO3 solution because the concentration of fluoride ions in the extract is below the detection limit of the AgNO3 solution. Fluoride ions have a very low reactivity with silver ions compared to other halide ions like chloride, bromide, and iodide, so they do not form a precipitate with AgNO3 under the conditions of the test.
