When the temperature of a reaction is rasied by `10^(@)C` for `Sb _(2) S_(3)` sol is

Options

A. `Na_(2) SO_(4)`
B. `Al_(2) (SO_(4))_(2)`
C. `NH_(4) Cl`
D. `NaCl`

Answer

B

Explanation

Given,
`Sb_(2) S_(3)` solution,
It is a negative solution containing negative charges on its surface.
Thus, it can easily bind with positive charges.
From the given option, `Al _(2) (SO_(4))_(3)` contains highest positive charge density `(al ^(3+)` ion).
`Al (SO_(4)) _(3)` is most effecitive conagulating agent.
