Which of the following will give maximum ions in solution ?

Options

A. `KI_(3)`
B. `CuSO_(4)`
C. `FeCl_(3)`
D. `K_(2)HgI_(4)`

Answer

C

Explanation

`(A)" "KI_(3) hArr K^(+)+I_(3)^(-)" "`(Two ions)
`(B) CuSO_(4)hArr Cu^(2+)+SO_(4)^(2-)" "`(Two ions )
`(C ) FeCl_(3) hArr Fe^(3+)+Cl^(-) " "`(Four ions )
`(D) K_2)[HgI_(4)] hArr 2K^(+)+[HgI_(4)]^(-)" "` (Three ions )
