Question

Write the precipitation reaction for barium carbonate in aqueous solution: Use the pull-down menus to specify the state of each reactant and product. Is barium carbonate considered soluble or not soluble ? A. Soluble B. Not soluble

Answer 1

1.Sol :-

The balanced precipitation reaction is :

Ba2+ (aq) + CO32- (aq) -------------------> BaCO3 (s)

Here, barium carbonate (BaCO3) form precipitates which shows that BaCO3 is not soluble in water.

--------------------

2.Sol :-

The value of solubility product constant (ksp) for Fe(OH)2 is = 2.0 x 10-15

The balanced reaction that corresponds to the Ksp value is :

Fe(OH)2 (s) -------------------> Fe2+ (aq) + 2OH- (aq)
