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

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

the objects have the same charge is correct.
