What is the basicity of EDTA?
EDTA (ethylenediaminetetraacetic acid) is a hexadentate ligand that can donate six pairs of electrons to form coordinate bonds with metal ions. It acts as a chelating agent due to its ability to form multiple bonds with a metal ion. The basicity of EDTA is high because it can donate multiple protons to form stable complexes with metal ions.
How many moles of Ca and Fe respectively could EDTA chelate?
1 mole of EDTA will chelate with 1 mole of Ca2+ ions or 1 mole of Fe2+ or Fe3+ ions.
Why PH 10 is maintain in complexometric titration?
A pH of 10 is maintained in complexometric titrations because it ensures the stability of metal-ligand complexes. At this pH, the metal ion forms stable complexes with the titrant (EDTA) while minimizing interference from other ions. Additionally, a pH of 10 helps to maintain appropriate solubility of the metal-ligand complexes for accurate endpoint detection.
Is NH3 a ligand?
Yes, NH3 is a ligand. It can act as a ligand by donating a pair of electrons to form coordinate bonds with a central metal atom or ion in a coordination complex.
What is the charge of the NH3 ligand in coordination complexes?
The NH3 ligand in coordination complexes typically has a charge of 0.
What is the basicity of EDTA?
EDTA (ethylenediaminetetraacetic acid) is a hexadentate ligand that can donate six pairs of electrons to form coordinate bonds with metal ions. It acts as a chelating agent due to its ability to form multiple bonds with a metal ion. The basicity of EDTA is high because it can donate multiple protons to form stable complexes with metal ions.
Is EDTA a sham?
No, EDTA is a tetradentate ligand.Some use that people are claiming for it may or may not be a sham (you'd need to give more details), but the compound itself is definitely real.
What is normality factor of0.05m edta?
The normality factor of a solution is determined by the number of reactive species that participate in a reaction. For EDTA (ethylenediaminetetraacetic acid), which is a hexadentate ligand that can chelate metal ions, the normality is typically calculated based on the number of moles of reactive sites available for binding. In a 0.05 M EDTA solution, since it can bind up to six metal ions, the normality would be 0.30 N (0.05 M × 6), assuming full reactivity.
How many moles of Ca and Fe respectively could EDTA chelate?
1 mole of EDTA will chelate with 1 mole of Ca2+ ions or 1 mole of Fe2+ or Fe3+ ions.
What is the structure of edta and ebt?
The structure of EDTA (ethylenediaminetetraacetic acid) consists of four carboxylic acid groups and two amine groups attached to a central metal ion binding site. EBT (Eriochrome Black T) is a tridentate ligand with three oxygen atoms in the ligand structure that can form complexes with metal ions.
Is legand EDTA is bidentate?
Yes, EDTA is a bidentate ligand, meaning it can form two coordination bonds with a metal ion. The two pairs of lone electron pairs on the nitrogen atoms in the EDTA molecule allow it to coordinate with metal ions in a chelation complex.
How many electrons are added to Zn plus by the coordinate- covalent bonds in the complex Zn-EDTA?
EDTA has 6 lone pairs of electrons four from oxygen atoms and two from lone pairs on nitrogen. IN complex ions all boncds are dative covalent so both electrons come from the ligand ion this case edta. so the answer is 6 electron pairs (12 electrons) are added
Why PH 10 is maintain in complexometric titration?
A pH of 10 is maintained in complexometric titrations because it ensures the stability of metal-ligand complexes. At this pH, the metal ion forms stable complexes with the titrant (EDTA) while minimizing interference from other ions. Additionally, a pH of 10 helps to maintain appropriate solubility of the metal-ligand complexes for accurate endpoint detection.
What kind of ligand is oxalic acid?
generally a bidentate, dianionic ligand
Write down the reaction equation of Zn2 plus and EDTA?
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
Is sulphate a ligand in chemistry?
yes , it is a flexidentate ligand its denticity can be one or two
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
