What kind of reaction take place between the calcium and EDTA?
The reaction between calcium and EDTA is a complexation reaction in which the EDTA molecule binds to the calcium ion, forming a stable, water-soluble complex. This reaction is used in titrations to determine the concentration of calcium in a sample.
What would be a better alternative to zinc sulphate as a primary standard for EDTA?
A better alternative to zinc sulfate as a primary standard for EDTA titrations is typically disodium hydrogen phosphate dihydrate (Na2HPO4∙2H2O), also known as disodium phosphate. This compound is preferred due to its higher purity, stability, and lower tendency to form complexes with EDTA compared to zinc sulfate.
Is CaF2 a covalent compound?
No, CaF2 is an ionic compound. Ionic compounds are typically formed between a metal (like calcium) and a non-metal (like fluorine), resulting in the transfer of electrons from the metal to the non-metal to form ions. In the case of CaF2, calcium (Ca) is a metal and fluorine (F) is a non-metal.
Which is more stable EDTA calcium or magnesium?
EDTA forms more stable complexes with calcium than with magnesium. This is due to the higher charge density and smaller size of the calcium ion, which allows it to form stronger bonds with the EDTA molecule.
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.
Is disodium edta organic or inorganic?
it is organic
Is calcium disodium a leavening agent?
Calcium disodium, specifically calcium disodium EDTA, is not a leavening agent. Leavening agents, such as baking soda or baking powder, help baked goods rise by producing gas during the baking process. Calcium disodium EDTA is primarily used as a preservative and chelating agent in food and pharmaceuticals, rather than for leavening.
What is the reaction of calcium carbonate and disodium edetate?
The reaction between calcium carbonate (CaCO₃) and disodium edetate (Na₂EDTA) involves the chelation of calcium ions by EDTA. When disodium edetate is added to a solution containing calcium carbonate, it forms a stable complex with the calcium ions, resulting in the dissolution of calcium carbonate. This reaction is often used in analytical chemistry to quantify calcium levels or in various applications where calcium removal is desired.
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 (Na2C10H14N2Na2·2H2O) in enough water to make 1 liter of solution.
What is disodium edta?
Used in solarcaine.

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.
What is the antidote for calcium gluconate?
The antidote for calcium gluconate toxicity is calcium disodium versenate (EDTA). It works by chelating the excess calcium ions and helping the body eliminate them. It is important to consult a healthcare professional for proper management of calcium gluconate toxicity.
How much gm of disodium EDTA to prepare O5 M disodium EDTA?
To prepare a 0.5 M solution of disodium EDTA, you would need to calculate the molar mass of disodium EDTA (approximately 372.24 g/mol) and then use the formula: (given concentration x volume in liters) / molar mass = mass needed. So, for 0.5 M solution: (0.5 mol/L x 1 L) / 372.24 g/mol = 0.00134 kg or 1.34 g of disodium EDTA is needed.
What is the balanced chemical equation for nickel ii sulphate and disodium salt of edta?
NiSO4 + Na2(edta) -----> Ni(edta) + Na2SO4
Is disodium edta a preservative?
Disodium EDTA is not a preservative itself but is often used in cosmetics and personal care products to enhance the effectiveness of preservatives by reducing the presence of metal ions that can degrade them.
What is the difference between disodium edetate and EDTA?
EDTA is in full name writing: 'Ethylenediaminetetraacetic acid', a tetraprotic (H+) acid.It's IUPAC name is 2,2',2'',2'''-(Ethane-1,2-diyldinitrilo)-tetra-acetic acidShorthanded: H4EDT-acetate, or H4EdetateSo consequently disodium edetate is Na2H2EDT-acetate, or Na2H2Edetate, thus a 'better' name would be disodium dihydrogen edetate
