Question

Write the ionic equation for dissolution and the solubility product (Ksp) expression for each of the following slightly soluble ionic compounds. (For the ionic equations, include states-of-matter under the given conditions in your answer. Solubility equilibrium expressions take the general form: K CA +]a Bm-lb. Subscripts and superscripts that include letters must be enclosed in braces ty. For example: Ksp CA 12. B2-1 must be typed using K_tspy CA 2. B 2-1 (a) Ag2Cro4 Net ionic equation g Help chemPad Greek Solubility product expression g Help chemPad Greek (b) SrSO Net ionic equation g Help chemPad Greek Solubility product expression g Help chemPad Greek (c) Mn(OH) Net ionic equation g Help chemPad

Explanation / Answer

a)
Ag2CrO4 (s) <----> 2Ag+ (aq) + CrO42- (aq)

Ksp = [Ag+]2 [CrO42-]

b)
SrSO4 (s) <----> Sr2+(aq) + SO42- (aq)

Ksp = [Sr2+] [SO42-]

c)
Mn(OH)2 <---> Mn2+ (aq) + 2OH- (aq)

Ksp = [Mn2+][OH-]2

d)
Sr3(PO4)2 (s)   <---> 3Sr2+ (aq) + 2PO43- (aq)

Ksp = [Sr2+]3 [PO43-]2
