What is the principal of disodium edta?
EDTA -Ethylene Diamine Tetra Acetic acid is a very powerful chelating agent and will thus complex most metals. However, it is not very soluble in water. The disodium salt of EDTA is and thus making a solution of this is much easier. If you have a known strength solution of EDTA disodium salt, it can then be used as a titrating solution for unknown metals salts.
What is disodium salt?
A salt containing two atoms of sodium; for example disodium sulfate - Na2SO4.
As edta dissolves in water the h will increase to achieve a pH 8.0 would you need to add hcl or naoh?
you have to add naoh because in water only sodium salt of EDTA will dissolve.

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
