At 25^(@)C, the K(sp) value of Fe(OH)(2)...

At `25^(@)C`, the `K_(sp)` value of `Fe(OH)_(2)` in aquoeus solution is `3.8 xx 10^(-38)`. The solubility of `Fe^(3+)` ions will increases when

A

`P^(H)` is increased

B

`P^(H)` is `7`

C

`P^(H)` is decreased

D

`P^(H) = 14`

Text Solution

Verified by Experts

The correct Answer is:
C
In acidic solution, `OH^(-)` ins are neutrarlized with `H^(+)` ions then equailibrium shift to forward direction.

If a springly soluble salt is placed in water, after some time an equilibrium is established when the rate of dissolution of ions form the soid equal to the rate of precipitation of ions from the saturated solution at a particular temperature. Thus, a dynamic equilibrium exists between the undissociated solid species and the dissolved ionic species in a saturated and the dissolved ionic species in a saturated solution at a particular temperature. For example, in AgCl , we have the following equilibrium: AgCl_((aq.)) Ag_((aq))^(+) + Cl_((aq))^(-) The equilibrium constant K_(eq) = ([Ag^(+)][Cl^(-)])/([AgCl]) K_(eq) xx [AgCl] = [Ag^(+)] [Cl^(-)] rArr K_(sp) (AgCl) = [Ag^(+)][Cl^(-)]"........"(A)" :' [AgCl] is constant If there would not have been a saturated solution, then from equation (A), Keq. [AgCl] ne K_(sp) , but K_(eq).[AgCl] = Q_(AgCl) , where Q is ionic product, it implies that for a saturated solution, Q = K_(sp) K_(sp) is temperature dependent. When Q lt K_(sp) , then the solution is unsaturated and there will be no precipitate formation. When Q = K_(sp) , then solution will be saturated, no and ppt. will be formed When Q gt K_(sp) , the solution will be supersaturated and there will be formation precipitate.
