MY and NY
3
, two nearly insoluble salts have the same K
sp
values of 6.2 × 10
-13
at room temperature. Which statement would be true in regard to MY and NY
3
?
(1). The molar solubility of MY in water is less than of NY
3
(2). The salts MY and NY
3
are more soluble in 0.5 M KY than in pure water
(3). The addition of the salt of KY to solution of MY and NY
3
will have no effect on their solubilities
(4). The molar solubilities of MY and NY
3
in water are identical
