The generic metal hydroxide M(OH)2
has Ksp
= 5.65×10−12. (NOTE: In this particular problem, because of the magnitude of the Ksp
and the stoichiometry of the compound, the contribution of OH−
from water can be ignored. However, this may not always be the case.)
What is the solubility of M(OH)2
in a 0.202 M
solution of M(NO3)2
?
