For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.) A. Pby(PO42 B. Cr(OH)3 C. Cas D. Fe(OH)3 1. calcium phosphate 2. manganese(II) carbonate Write the expression for K in terms of the solubility,s, for each salt, when dissolved in water. calcium phosphate manganese(II) carbonate Ksp Note: Mliply ut my er nd Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s

Explanation / Answer

1)

1. calcium phosphate = A

2. manganese(II) carbonate   = c

2) Ksp of Ca3(PO4)2 = (3S)^3(2S)^2 = 108S^5

   
   Ksp of MnCO3 = S^2

1. Mg(OH)2 is more soluble than = D , c

2. Mg(OH)2 is less soluble than = A

1. AgBr is more soluble than = A,B,C

2. AgBr is less soluble than = D
