Which one of the following compounds in aqueous solution gives a white precipitate with perchloric acid?

Options

A. NaCl
B. KCI
C. `MgCl_(2)`
D. `FeCl_(3)`

Answer

(b)

Explanation

As `K^(+)` ion in KCl is larger than `Na^(+), Mg^(+) and Fe^(3+)` ions, it forms a white precipitate on reacting with `CIO_(4)^(-)` ions.
