The ksp for zn(oh)2 is 5.0 x 10-17. determine the molar solubility of zn(oh)2 in a buffer solution with a ph of 11.5.
a) 5.0 x 106
b) 1.2 x 10-12
c) 1.6 x 10-14
d) 5.0 x 10-12
e) 5.0 x 10-17

Answer : The correct option is, (d)

Explanation :

First we have to calculate the concentration.

Now we have to calculate the concentration.

Now we have to calculate the molar solubility of .

The balanced equilibrium reaction will be:

The expression for solubility constant for this reaction will be,

Now put all the given values in this expression, we get:

Therefore, the molar solubility of is,

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
