Why is a solution containing a metal ion buffered before titration with EDTA?

Buffering the solution containing a metal ion before titration with EDTA helps maintain a constant pH, which is crucial for the accuracy and precision of the titration. The buffering prevents large pH changes that could affect the formation of metal-EDTA complexes and lead to errors in the titration results.


Is EDTA is water soluble if not than how will you prepare your solution?

Yes, EDTA is water-soluble. To prepare a solution, you can simply add the desired amount of EDTA powder to water and stir until it is completely dissolved. If you encounter issues with solubility, you can adjust the pH of the solution using sodium hydroxide or hydrochloric acid to help dissolve the EDTA.


How many grams of EDTA do you add to make a 3.7 percent EDTA solution?

To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.


Is sodium chromate the same as edta?

No, sodium chromate and EDTA (ethylenediaminetetraacetic acid) are not the same. Sodium chromate is a chemical compound containing sodium and chromium, while EDTA is a chelating agent often used in analytical chemistry and as a food additive or in medical applications.


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 are the ingredients in Pantene classic care shampoo?

Water, Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Sodium Chloride, Glycol Distearate, Cocamidopropyl Betaine, Dimethicone, Citric Acid, Cocamide MEA, Sodium Citrate, Fragrance, Sodium Xylene Sulfonate, Sodium Benzoate, Guar Hydroxypropyltrimonium Chloride, Tetrasodium EDTA, Panthenol, Panthenyl Ethyl Ether, Methylchloroisothiazolinone, Methylisothiazolinone


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.


How can you prepare 100mM EDTA?

To prepare 100mM EDTA solution, dissolve 37.2g of EDTA disodium salt dihydrate in 1 liter of water. Make sure the pH is adjusted to around 8.0 with sodium hydroxide or hydrochloric acid if needed. Mix well until EDTA is fully dissolved.


Why is Ammonia solution added while preparing EDTA solution?

Ammonia solution is added to increase the pH of the solution to create a favorable environment for the formation of stable metal-EDTA complexes. This helps in improving the efficiency of complexation and enhances the chelating properties of EDTA.


How much gm of disodium edta require to prepare 0.05 m disodium edta solution?

To prepare a 0.05 M disodium EDTA solution, you would need to dissolve 3.72 grams of disodium EDTA dihydrate (Na2C10H14N2Na2ยท2H2O) in enough water to make 1 liter of solution.


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 does standardise EDTA mean?

Standardizing EDTA refers to determining the exact concentration of the EDTA solution by titrating it against a known concentration of a metal ion solution. This process ensures that the EDTA solution is accurately diluted or concentrated to achieve consistent and reliable results in complexometric titrations.
