What is the chemical reaction of EDTA?
In the presence of sulfuric acid, this compound then reacts with ethylenediamine forming an intermediate compound that eventually reacts with water to form EDTA. Solid EDTA is readily dissolved in water where it can form multiple chemical bonds with many metal ions in a solution, in effect tying up the metal ions.
What are the 2 chemical reactions?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
What does a chemical reaction lead to?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What is EDTA in Analytical Chemistry?
In analytical chemistry, EDTA is used in complexometric titrations and analysis of water hardness or as a masking agent to sequester metal ions that would interfere with the analyses.

What are the 4 types of chemical reaction?
Four basic types Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
What happens when EDTA reacts with metal?
Reaction of EDTA with Metal Ions Except for the alkali metal ions of charge +1, most metal ions in aqueous solution react with EDTA to form complex ions in solution. The three-dimensional shape of one such complex ion is illustrated in Harris, page 265. All metal ions react with EDTA in the mol ratio of 1 to 1. For zinc ions in water:
How do you titrate lead with EDTA?
Lead may be titrated with EDTA over several pH ranges using a variety of indicators. by direct or back procedures. In This experiment, we describe the determination of lead. by Complexometric back titration at pH 10 using Eriochrome black T as an indicator.
How do you find the formation constant of EDTA?
Conditional Formation Constant The formation constant Kf = [MYn − 4]/[Mn+][Y4−] describes the reaction between Y4− and a metal ion. As seen in the fractional composition diagram, most EDTA is not Y4− below pH 10.37. The species HY3−, H2Y2−, and so on, predominate at lower pH. From the definition
What is KF in EDTA reaction?
EDTA Complexes The equilibrium constant for the reaction of a metal with a ligand is called the formation constant, Kf, or the stability constant: In many transition metal complexes, EDTA engulfs the metal ion, forming the six- coordinate species.
