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.
Is benzoic acid react with sodium bicarbonate?
Yes, benzoic acid will react with sodium bicarbonate to produce sodium benzoate, carbon dioxide, and water. This reaction can be used to extract benzoic acid from a mixture as it is relatively insoluble in water but soluble in sodium bicarbonate solution.

What is chocolate extract?
Chocolate extract is very like vanilla extract in its make-up that is, the essence of the bean distilled in a solution of water and alcohol.
Why is aqueous solution sodium extract alkaline?
Because this solution contain sodium hydroxide.
How can you extract silica from a uranium bearing solution?
By filtration

How do you extract water from salt solution?
Water is released by evaporation.
How do you extract rayon threads from Hcl solution?
Very carefully.
Why a base is taken in pipette?
The purpose is to extract a known volume of solution.
Does green tea perfume have side effects?
Green Tea perfume is made with green tea extract. This is a homeopathic solution and should have no adverse side effects. Always check with a physician if you think you may have an allergic reaction.

How is lomatium taken?
Lomatium is available as an extract, as a tincture, and in capsule form. Fresh root extract in an alcohol solution is believed to be the most effective remedy.
Experiment on the effect of the PH of enzymatic reaction using hydrogen peroxide and extract of spinach leaf?
To investigate the effect of pH on the enzymatic reaction with hydrogen peroxide and spinach leaf extract, set up multiple test tubes with varying pH solutions. Then, add equal amounts of hydrogen peroxide and spinach leaf extract to each test tube and observe the rate of reaction. Measure the rate of reaction by recording the production of gas or color change over a set period of time. This will provide insights into how pH influences the enzyme activity in the reaction.
