Question

is [CrO4]2- ions , ionize in water or buufer to cr 6+?!

Answer 1

Oxygen is always \(O^{2-}\) with some exception, but not this.
So
\[\huge [Cr^{+6}O_4^{-2}]^{-2}\]

Answer 2

would you mean it can be ionize?!

Answer 3

or it canot?

Answer 4

Isn't that ionized already?

Answer 5

i think it cannot be ionise to cr 6+ and oxygen, but i am nt sure !!!!!!!!!

Answer 6

You mean
\[CrO_4^{-2} \rightarrow Cr^{+6}+4O^{-2}\]

Answer 7

yes

Answer 8

cr6+ + 302-

Answer 9

Its
cr6+ + 402-

Answer 10

it can be occure in solution?!!!

Answer 11

do you have any refrence for it ?

Answer 12

The original compound for example is
\[ K_2CrO_4\]
Its soluble, so when ionised with water it forms ions like
\[2K^{+} +CrO_4^{2-}\]

Answer 13

I don't think \(CrO_4^{-2} \rightarrow Cr^{+6}+4O^{-2}\) will happen

Answer 14

ok thanks
