Can i use phenolphethalein for EDTA against calcium chloride?
No, phenolphthalein is not suitable for titrating EDTA against calcium chloride because phenolphthalein is a pH indicator that changes color when the pH of a solution changes, while the reaction between EDTA and calcium ions does not involve a significant change in pH. Instead, a different indicator like Eriochrome Black T is commonly used in complexometric titrations involving EDTA and metal ions like calcium.
Difference between precipitation titration and complexometric titration?
In precipitation titration, the formation of a solid precipitate is used to determine the endpoint of the titration, while in complexometric titration, a complex formation reaction is used to determine the endpoint. Precipitation titration is often used for specific ion determinations, while complexometric titration is used for determining metal ions by forming stable complexes with titrant.
What is the definition for complexometric titrations?
Complexometric titrations are a type of volumetric analysis that involves the use of a complexing agent (such as EDTA) to form stable complexes with metal ions in solution. By titrating with a solution of known concentration of the complexing agent, the endpoint of the reaction can be determined based on a color change or other indicator, allowing for the quantitative determination of the metal ion concentration.
What kind of indicators are used in precipitation titration?
Indicators used in precipitation titrations are typically complexometric indicators that form colored complexes with the analyte ions. These indicators change color when the endpoint of the titration is reached, signaling the completion of the precipitation reaction. Common complexometric indicators include EDTA, Eriochrome Black T, and Calconcarboxylic acid.
How was EDTA discovered in Germany?
EDTA was discovered in Germany in 1935 by Ferdinand Munz. He was working for the German chemical company I.G. Farben when he synthesized EDTA while researching new stabilizers for painters' dyes. Munz found that EDTA had a strong chelating ability, which led to its development and widespread use in various industries.

Why do you use calcium carbonate in complexometric titration?
The affirmation is not correct.
Why do you only use calcium carbonate in complexometric titration?
The affirmation is not correct.
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
When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.

What is use of Versene in inorganic chemistry?
Versene is a trade name for a chelating agent, a sodium salt of EDTA, ethylenediaminetetraacetic acid. This molecule is a polydentate ligand with 6 points where it can coordinate to a central metal ion. It binds readily to many cations and is used in the laboratory in complexometric titrations. It has many applications in for example medicine and industry.

Why is disodium salt of EDTA preferred to EDTA?
The disodium salt of EDTA is preferred over EDTA because it is more soluble in water, which makes it easier to handle and use in aqueous solutions. Additionally, the disodium salt has a higher stability in a wider range of pH levels compared to EDTA alone, making it more versatile for various applications.
Why is phenolphthalein indicator not used in EDTA titration?
Phenolphthalein is not suitable for use in EDTA titration because it changes color at a pH range that is much lower than the pH range at which the EDTA-metal complex formation occurs. EDTA titration typically requires indicators that change color in a more acidic pH range.
