Solid barium sulfate is placed into a beaker to form a saturated solution of barium sulfate. the solution has a barium concentration of 1x10-5m. what is ksp for barium sulfate?

Answer : The value of for barium sulfate is,

Solution :

The balanced equilibrium reaction will be,

The expression for solubility constant for this reaction will be,

Let the concentration of barium ion and sulfate ion be, 's'.

From the balanced equilibrium reaction, we conclude that the concentration of sulfate will be equal to the concentration of barium.

Now put all the value of in the above expression, we get the value of solubility constant for barium sulfate.

Therefore, the value of for barium sulfate is,

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.
