Why do we add potassium carbonate during caffeine extraction?
Tannins are neutralized by potassium carbonate, remain in the water solution and caffeine is easily extracted with methylene chloride.
What is the purpose of Trichloroacetic acid in DNA extraction?
Trichloroacetic acid is used for precipitation of the DNA during its extraction.
What purpose does sodium carbonate serve during the extraction of caffeine from tea leaves?
The reason sodium carbonate is added to the tea is because the tannins are acidic and sodium carbonate is a base, so when sodium carbonate is added to the tea water mixture, the acids are converted to their sodium salts which are highly soluble in water.
Why it is necessary to saturate sodium chloride and butanol during solvent extraction?
The saturation of butanol with sodium chloride is to avoid further ionic or inorganic compound to dissolve, now only non polar or organic compounds may dissolve in butanol during extraction.
Why grind the liver in a DNA extraction lab?
the purpose of grinding any substance during dna extraction is cell loosening.
Why is gentle shaking necessary during the extraction of caffeine from tea?
This is necessary to ensure the solvent moves amongst the tea leaf particles to extract all the caffeine. It agitates the tea leaf particles and separates any that are clumping together and hindering efficient extraction.
What the purpose of adding sodium chloride during hard soap preparation?
Adding sodium chloride soap is precipitated.
Why is chloroform at the bottom during extraction process with benzoic acid and sodium chloride mixture in water?
Because it is immiscible and has a greater density.
Why is sodium carbonate added during solvent extraction?
It is usually added during an extraction in order to make the solution alkaline. Often times, this aids in the efficiency of the extraction.
How is sodium chloride used during a electrocardiogram?
Sodium chloride is not used during electrocardiogram.
Which of the two layers that are formed during the extraction is dichloromethane?
aqueous layer
Why did the sodium chloride remain unchanged?
Sodium chloride may be changed during chemical reactions.
