What is the role of Rochelle salt in the Fehling's reagent?
Fehling's solution is prepared just before use by mixing equal volumes of two previously prepared solutions, one containing about 70 grams cupric sulfate pentahydrate per liter of solution and the other containing about 350 grams Rochelle salt (potassium sodium tartrate tetrahydrate) and 100 grams sodium hydroxide per liter of solution. The cupric ion (complexed with tartrate ion) is reduced to cuprous ion by the aldehyde (which is oxidized) and precipitates as cuprous oxide (Cu2O). So the tartrate part of Rochelle salt is the key reactant. In the case of sodium citrate: the cupric ion (complexed with citrate ions) is reduced to cuprous ion by the aldehyde group (which is oxidized), and precipitates as cuprous oxide, Cu2O. Thus the citrate is key to the reaction.
What is the chemical symbol for citrate?
Any salt of citric acid. Citrate is the first intermediate of the citric acid cycle and tricarboxylic acid (TCA) cycle. It also plays an important role in fatty acid synthesis which takes place in the cytoplasm.
What is the role of sodium potassium tartrate in Fehling's solution?
The tartarate ions, by complexing copper prevent the formation of Cu(OH)2 from the reaction of CuSO4.2H2O and NaOH present in the solution
Is there any difference between ORS and Electral powder?
Electral is WHO based ORS (Oral Rehydration Solution) formula. The formula is basically a combination of Dextrose and a number of essential electrolytes like Sodium Chloride, Potassium Chloride, and Sodium Citrate. These electrolytes play a major role in conducting nervous impulses, contracting muscles, keeping you hydrated, and regulating your body's pH levels. Electral is used for the replacement of fluid and these electrolytes and maintenance of hydration in diarrhea, vomiting, and other conditions where there is a loss of water and electrolytes. Hence there is no difference between ORS and Electral powder.
What is the role of NaOH in the formation of hippuric acid?
Glycine intracts with one mole of Bezoyl chloride in the presence of 10% (w/v) solution to yield hippuric acid with the elimination of one mole of hydrochloric acid. The excess of 10% NaOH solution serves two purposes, first; to remove unreacted benzoyl chloride. The NaOH solution hydrolyses the excess of benzoyl chloride present in reaction mixture, thereby resulting in formation of sodium chloride and sodium benzoate, which being water soluble remains in solution. Secondly the hydrochloric acid eliminated reacts with NaOH to yield NaCl. Both sodium benzoate and sodium chloride are water soluble, whereas the desired product hippuric acid being insoluble may be separated easily.
How can sodium chloride buffering the edta solution?
In this case sodium chloride does not have any buffering role.

What is the role of NaCl in TBST buffer?
In this case sodium chloride form an isotonic solution.
What does the role of salts in hydrogen production?
Hydrogen can be obtained by electrolysis of sodium chloride water solution.
Does magnesium citrate dissolve food in your stomach?
Magnesium citrate is used as a laxative to relieve constipation. Magnesium is important to muscle and nerve health, but plays no role in digestion.
What is the role of anhydrous sulfate?
Anhydrous sodium sulfate is considered as a drying agent. It is used in expirements to remove water from a solution or during an expirement. hope this helps.

The role of sodium chloride in extraction method?
Brine (saturated sodium chloride solution) is usually the last solution used in an aqueous wash to help remove trace amounts of water (and anything water soluble) from the organic layer. Many chemists skip this step however, since sodium sulfate or manganese sulfate is used to remove water from the organic layer anyway, after the organic layer is separated.

Role of sodium chloride in DNA extraction?
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA.
