Sodium citrate acts as a stabilizing agent in Benedict's solution, helping to maintain its pH and prevent the formation of copper oxide precipitates. This allows for more accurate measurements of reducing sugars in the presence of other compounds.
Sodium citrate is generally considered safe when consumed in appropriate amounts as a food additive for its role as a preservative and flavor enhancer. It is commonly used as an acidity regulator in various processed foods and beverages. However, excessive intake of sodium citrate may contribute to increased sodium consumption, which can be harmful for individuals with certain health conditions such as hypertension.
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.
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.
The hydroxide ion (OH-) is responsible for making a solution basic. It can combine with hydrogen ions (H+) to form water (H2O), reducing the concentration of free hydrogen ions and increasing the pH of the solution. Sodium ions (Na+) do not play a direct role in determining the pH of a solution.
Sodium potassium tartrate, also known as Rochelle salt, is a complexing agent in Fehling's solution. It helps to stabilize the cupric ions in the solution and prevents them from precipitating out. This is important for maintaining the reactivity of the solution in detecting reducing sugars through a redox reaction.

In this case sodium chloride does not have any buffering role.
Citrate is a compound that serves as an intermediate in the citric acid cycle, a central metabolic pathway in all aerobic organisms. It plays a key role in the metabolism of carbohydrates, fats, and proteins by participating in various metabolic reactions. Additionally, citrate is commonly used in food and beverage production as a preservative and flavoring agent.
In this case sodium chloride form an isotonic solution.
Hydrogen can be obtained by electrolysis of sodium chloride water solution.

Citrate Permease is an enzyme that is responsible for transporting citrate inside the cell. Some bacteria have this enzyme while others do not. You can test for the presence of citrate permease by performing a Simmon's Citrate biochemical test.
Magnesium citrate is used as a laxative to relieve constipation. Magnesium is important to muscle and nerve health, but plays no role in digestion.

Citrate acts as a citrate chelator and plays a significant role in metabolic processes, particularly in the citric acid cycle (Krebs cycle). It can inhibit the enzyme phosphofructokinase, thereby regulating glycolysis and influencing energy production. Additionally, citrate can help prevent the formation of kidney stones by binding to calcium in the urine. Its role as a buffer also aids in maintaining pH balance in various biological systems.
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.
Sodium phosphate (Na2HPO4) is a buffering agent commonly used in biological and biochemical applications to help maintain a stable pH level. When dissolved in solution, it dissociates into sodium ions (Na+) and phosphate ions (HPO4^2-), which can help regulate the acidity of the solution by accepting or donating protons (H+).
