Consider a saturated aqueous solution of chromium (III) hydroxide, Cr(OH)3(s)?Cr3+(aq)+3OH?(aq) How will each of the following changes affect an equilibrium mixture?
C) we know that
solids does not affect the equilibrium
So
adding solid Cr(OH)3 has no affect on the equilibrium
D)
now
HCl is added
HCl--> H+ + Cl-
now
these H+ removes OH- from the equilibrium by the equation
H+ + OH- --> H20
so
by adding HCl , OH- are removed
now
according to Le Chatlier principle
the equilibrium will shift in a direction to counter the change
in this case
conc of OH- ions is decreasing ,
So to increase the conc of OH- ions,
the equilibrium will shift towards the products

3. Consider a room temperature, 100mL aqueous solution saturated with the ionic compound beryllium hydroxide Be(OH)2 due to the addition of 10g of Be(OH)2; MM-43.02 g-mol-1. KsP-2.0 x10-8 Use this provided information to calculate the pH of this saturated solution. Hints: Due to the low solubility product, very little of this compound actually dissolves in H20. Go ahead and assume all activity coefficients are equal to 1.0 for this problem. This seems like a good opportunity to apply the ICE...
