What is disodium EDTA dihydrate?

Description. EDTA disodium salt dihydrate is a hydrate that is the dihydrate form of EDTA disodium salt. It has a role as a chelator and an anticoagulant.

What is N factor in equivalent weight?

n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is its basicity,ie, no of replaceable hydrogen ion per molecule.

How do you calculate equivalent?

To find the equivalent of an acid, divide the acid’s molar mass by the number of protons. Here is a simple example using sulfuric acid: (1×2+32×1+16×4)/2 = 49 g/mol. Finding the equivalent of a salt is also simple: multiply the number of metal atoms by their oxidation state, then divide its molar mass by the result.

Why do we use disodium EDTA?

Edetate disodium (EDTA) is a chelating (KEE-late-ing) agent. A chelating agent is capable of removing a heavy metal, such as lead or mercury, from the blood. EDTA is used to lower blood levels of calcium when they have become dangerously high.

Is disodium EDTA organic or inorganic?

All rights reserved. (Elements & Compounds) ethylenediaminetetra-acetic acid; a colourless crystalline slightly soluble organic compound used in inorganic chemistry and biochemistry. It is a powerful chelating agent used to stabilize bleach in detergents.

Why is EDTA most soluble at a pH 8?

EDTA is essentially insoluble in water, and will only dissolve when neutralized with sodium hydroxide to a pH = 8.0 Standard stock solutions are 0.5M at pH 8.0. A 1M solution cannot be made.
