Buffer maintains the pH of the solution through out the reaction. To maintain high alkaline medium ammonia buffer is added to EDTA in analysis of hard water. It is necessary to keep the pH at about 10 for two reasons: (a) all reactions between metal ions and EDTA are pH dependent, and for divalent ions, solutions must be kept basic (and buffered) for the reaction to go to completion; (b) the eriochrome black T indicator requires a pH of 8 to 10 for the desired color change.

What is the need for an ammonical buffer solution in the determination of hardness of water by edta titration?
during the complexometric titration using edta it is very necessary to maintain the ph of the solution near about 10 so we use ammonium chloride buffer if we will not use this buffer dring the titration ph of sol. will ho lower side
Why we add buffer to standardization of ED-TA solution?
Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.

What is Buffer AE?
Buffer AE is a solution used in molecular biology to stabilize DNA and RNA. It typically contains chemicals such as Tris, EDTA, and water to maintain the stability and integrity of nucleic acids during storage or handling. Buffer AE is commonly used in protocols for DNA or RNA extraction and purification.
What is Buffer ATE?
Buffer ATE is a common buffer solution used in biological and biochemical laboratories. It typically consists of acetic acid, tris(hydroxymethyl)aminomethane (Tris), and EDTA (ethylenediaminetetraacetic acid). Buffer ATE is used to maintain a stable pH and prevent metal ion interference in experiments such as nucleic acid extraction or enzymatic reactions.
What is TNE buffer?
tris, EDTA (TE solution) and NaCl, TNE buffer is a buffer solution used in molecular biology, especially for DNA and RNA
Why you use pH 10 buffer in EDTA titration and the indicator paper not be put into the solution?
A pH 10 buffer is used in EDTA titrations to ensure that the reaction occurs at a consistent pH that is optimal for the formation of metal-EDTA complexes. The indicator paper is not added to the solution because the color change of the metal-EDTA complex is independent of pH and will occur naturally when all the metal ions are chelated by the EDTA.
Why buffer solution must be used for titration with EDTA?
A buffer solution must be used for titration with EDTA because it helps maintain a constant pH during the titration process. EDTA forms complexes with metal ions at specific pH levels, so maintaining a steady pH ensures accurate and reproducible results. Additionally, a buffer solution helps prevent changes in the pH that could interfere with the formation of the metal-EDTA complexes.

What is the use of buffer in EDTA titration?
In EDTA titration, a buffer solution is used to maintain a constant pH level throughout the titration process. This helps to ensure accurate and reproducible results by preventing any variations in the reaction due to changes in pH. The buffer solution typically contains an acidic species (such as acetic acid) and its conjugate base (such as sodium acetate) to maintain a stable pH around the optimal range for the reaction.
What is the function of tris and EDTA buffer?
Tris buffers provide a stable pH environment for biochemical reactions, while EDTA chelates metal ions to prevent enzymatic degradation. When used together, the Tris-EDTA (TE) buffer is commonly used for nucleic acid storage and as a buffer in molecular biology applications.
Role of EDTA in lysis buffer?
EDTA in lysis buffer helps to chelate divalent cations (such as Mg2+ and Ca2+) which are cofactors for nucleases, preventing degradation of nucleic acids. This helps to preserve the integrity of RNA and DNA during the lysis process.
Why must use buffer solution in titration involving EDTA?
EDTA is Ethydiaminotetraacetic acid. In some titrations, it is best to avoid any sharp pH changes(except in acid-base titrations, of course). Buffers are the right substances to help maintain a constant pH.
How do you measure permanent hardness by EDIT titration?
To measure permanent hardness by EDTA titration, first add a buffer solution to the water sample to maintain a stable pH. Then, titrate with standardized EDTA solution until the color changes indicating the endpoint. The volume of EDTA required to reach the endpoint can be used to calculate the concentration of the ions causing permanent hardness in the water.
What is Buffer AE?
Buffer AE is a solution used in molecular biology to stabilize DNA and RNA. It typically contains chemicals such as Tris, EDTA, and water to maintain the stability and integrity of nucleic acids during storage or handling. Buffer AE is commonly used in protocols for DNA or RNA extraction and purification.
