Chemistry Question on Solutions
The solubility product of Al2(SO4)3 is given by the expression
A
[Al3+][SO42−]
B
[Al3+]2[SO42−]
C
[Al3+]3[SO42−]2
D
[Al3+]2[SO42−]3
Answer
[Al3+]2[SO42−]3
Explanation
Solution
Ksp=[Al+3]2[SO4−2]3
The solubility product of Al2(SO4)3 is given by the expression
[Al3+][SO42−]
[Al3+]2[SO42−]
[Al3+]3[SO42−]2
[Al3+]2[SO42−]3
[Al3+]2[SO42−]3
Ksp=[Al+3]2[SO4−2]3
