Question

What do you mean by the statement like
Mn has +7 oxidation state?
Something like it has strong +ve electric field and attracts more ..like that? something with respect to that?

Answer 1

@chmvijay

Answer 2

i don't know what do u mean by +ve electric field ,is that effective nuclear charge? or ionic radii ?or polarizing power?
+7 mean it can loose Max those electrons in any redox reaction and get stable by noble gas configuration It mean is pore +vely charged bcoz u have removed 7 electron and still the same no of protons are there hence the +ve charge on it is very high :)

still u need anything more let me know

Answer 3

The oxide of higher oxidation state of the element is more acidic than that of lower oxidation state.Why?
This answer is in reference to that question(from p block)

Answer 4

the electrons config for elemental Mn is [Ar] \(4s^23d^5\)

\(Mn^{7+}\) would have lost all those 3d and 4s electrons, either through ionization or through binding with e deficient ligands ("oxidative addition") in terms of it's formal charge.

Answer 5

it mean they are LEWIS ACIDIC RIGHT :)
bcoz of electron deficient due to higher oxidation state :)

Answer 6

still confusion in MIND ?

Answer 7

can u please explain my answer...
The oxide of element of higher oxn. state will have a stronger +ve electric field and it will interact with water more strongly and hence pull electrons of OH bond more tightly.Therefore release of H+ becomes easy.

Answer 8

okok it will hydrolyze water to form H+
