At room temperature, MY and NY3, two nearly insoluble salts, have the same Ksp values of 6.2 x 10-13. The true statement regarding MY and NY3 is:

1. The molar solubility of MY in water is less than that of NY3.
2. The salts MY and NY3 are more soluble in 0.5 M KY than in pure water.
3. The addition of the salt of KY to a solution of MY and NY3 will have no effect on their solubilities.
4. The molar solubilities of MY and NY3 in water are identical.
