Why is buffer solution used in EDTA method?
Buffer maintains the pH of the solution through out the reaction. To maintain high alkaline medium ammonia buffer is added to EDTA in analysis of hard water. It is necessary to keep the pH at about 10 for two reasons: (a) all reactions between metal ions and EDTA are pH dependent, and for divalent ions, solutions must be kept basic (and buffered) for the reaction to go to completion; (b) the eriochrome black T indicator requires a pH of 8 to 10 for the desired color change.
Why EDTA is not dissolved in water?
EDTA is soluble in water.
Why we add buffer to standardization of ED-TA solution?
Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.
Is sodium chromate the same as edta?
No. Edta is Ethylenediaminetetraacetic acid
What is tertrasodium edta?
Tertrasodium EDTA is a chelating and preservative agent.
Why do buffers added in EDTA titration?
to maintain constant ph
Why ammonia is added in preparation of EDTA solution?
To maintain pH=10

Why must use buffer solution in titration involving EDTA?
EDTA is Ethydiaminotetraacetic acid. In some titrations, it is best to avoid any sharp pH changes(except in acid-base titrations, of course). Buffers are the right substances to help maintain a constant pH.
Why EDTA is not dissolved in water?
EDTA is soluble in water.
What is the basicity of EDTA?
the basicity of EDTA is 4
What is EDTA whole blood?
EDTA whole blood is whole blood that has been drawn into a tube with EDTA in it. The EDTA is added to transport samples and prevents the blood from clotting.
What is the optimal time to measure MPV in a edta specimen?
between one to four hours.
What kind of reaction take place between the calcium and EDTA?
complexation or chelation reaction
EDTA to remove calcium from the body which is responsible for hardening of cholesterol in the vessels?
Ethylenediaminetetraacetic acid (EDTA) is a chelating agent and can bind calcium. Exploitation of this property will enable removal of calcium from the body. Of course safety is paramount, and EDTA should not cause adverse health effects.

Is EDTA is water soluble?
Yes, EDTA is water soluble.
