Instead of sodium tartrate buffer, phosphate buffer can be used as an alternative. Phosphate buffer is widely employed in biochemical and molecular Biology applications due to its effective pH range and low ionic strength. It maintains a stable pH environment, making it suitable for various enzymatic reactions and biological assays. Additionally, Tris buffer is another common alternative that offers similar buffering capabilities.

What is the another name of Bohr's salt?
Another name for Bohr's salt is "potassium sodium tartrate," which is often used in chemistry as a buffer solution. It is commonly referred to as "Rochelle salt" and has applications in various fields, including food science and pharmaceuticals.
Is HCOOH and HCOONa a buffer?
Yes, in a 1:10 dilution of Na2CO3, and NaHCO3, the buffer capacity for basic solutions is 7E-4 and for acidic solutions, 1.2E-01
What is sorensens buffer?
Phosphate buffered saline is a buffer solution commonly used in biological research. It is a water-based salt solution containing sodium phosphate, sodium chloride and, in some formulations, potassium chloride and potassium phosphate. The osmolarity and ion concentrations of the solutions match those of the human body.
What is NA3PO4 in chemistry?
NA3PO4 is the chemical formula for sodium phosphate, which is a salt composed of sodium cations and phosphate anions. It is commonly used in laboratory applications, such as in buffer solutions or as a cleaning agent. Sodium phosphate has various forms with different stoichiometries, such as tribasic sodium phosphate (trisodium phosphate) or dodecahydrate sodium phosphate.
What is Buffer AL and what does it do?
Buffer AL is used in DNA extraction and causes cell lysis to expose the DNA. Buffer AL is used during DNA isolation using QIAamp and DNeasy protocols. Buffer AL is stable for 1 year when stored closed at room temperature (15-25°C). Preparation of Buffer AL/E is as such: Volume of Buffer AL (ml) Volume of 96-100% ethanol (ml) Bottle size (ml) 33 35 100 108 114 250 162 171 500 216 228 500
Why you use di sodium tartrate for calibration of Karl fisher?
Sodium tartrate is used in Karl Fischer titration to standardize the reagent and verify its accuracy. It helps to determine the exact amount of water present in the sodium tartrate sample, which can then be used to calculate the water content in other samples. This calibration ensures the reliability and precision of the Karl Fischer titration method.

Sodium acetate buffer?
Sodium acetate buffer is a commonly used buffer solution in biochemical and molecular biology laboratories. It consists of a mixture of sodium acetate and acetic acid, and helps maintain a stable pH when added to solutions. It is effective in the pH range of around 4.7 to 5.7.
What is function of tartrate?
Tartrate, specifically in the form of tartaric acid or its salts, serves several functions in various contexts. In food and beverage production, it acts as an acidulant and stabilizing agent, particularly in winemaking, where it helps to prevent the crystallization of potassium bitartrate. In the pharmaceutical industry, tartrate forms are used to enhance the solubility and absorption of certain medications. Additionally, tartrate is utilized in laboratory settings as a chelating agent and in buffer solutions.
What is an alternative component to sodium phosphate for a pH 6.2 buffer preparation?
Potassium dihydrogen phosphate can be used as an alternative to sodium phosphate for a pH 6.2 buffer preparation. It can help maintain the pH value close to 6.2 and is commonly used in biological and biochemical applications.
How many edible salts are there?
The most important is sodium chloride; persons with heart diseases can eat potassium chloride. Many other salts are used as food additives in very low concentrations: potassium iodate, potassium iodide, sodium citrate, sodium phosphates, sodium monoglutamate, sodium acetate, sodium tartrate, ammonium chloride etc.
What is acetic acid NaOAc?
Sodium acetate (NaOAc) is the sodium salt of acetic acid. It is a commonly used chemical compound in various industries and is often used as a buffer solution or as a food additive. Sodium acetate is also used in the textile industry as a fixing agent for dyes.
What is Na2B4O7?
Sodium tetraborate, also known as borax or sodium borate, is a salt with the chemical formula Na2B4O7. It is commonly used in cleaning products, adhesives, and as a buffer in chemical laboratories.
Can vinegar be used to make a buffer solution?
No, vinegar cannot be used to make a buffer solution. A buffer solution typically consists of a weak acid and its conjugate base, such as acetic acid and sodium acetate. Vinegar is a dilute solution of acetic acid only and lacks the necessary components to act as a buffer.
What can be used as a buffer for pH 12-13?
A commonly used buffer for pH 12-13 is a mixture of potassium hydrogen phthalate and sodium hydroxide. This combination helps maintain a stable pH in this alkaline range. Alternatively, a borate buffer system can also be used for pH around 12-13.
