Chromium(iii) hydroxide has ksp 1.6 x 10-30. what is the molar solubility of cr(oh)3 in a solution whose ph is maintained at 6.00?

Explanation:

Chemical reaction equation for is as follows.

As it is given that pH is 6. So, the concentration of hydrogen ions will be as follows.

             pH =

             antilog (-6) =

 and

                   =

                   =

Now, let us assume that the solubility is "s". Therefore,

                                     s    

Therefore, calculate the value of for this reaction as follows.

                        s =        

Thus, we can conclude that the molar solubility of is .

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
