How many grams of ba(io3)2 can be dissolved in 250. ml of distilled water at 25 oc ? note: ksp of ba(io3)2 is 1.57 × 10-9 and molar mass of ba(io3)2 = 487.1323 g/mol?

Explanation

Solid barium iodate and its ionic components are in a dynamic equilibrium when dissolved in an aqueous solution. Each mole of barium iodate dissolves to produce one mole of barium ions and two moles of iodate ions.

Thus

.

Given that

of from the question, and

as seen in the dissociation equilibrium,

of distilled water can thus dissolve up to

which corresponds to
