At room temperature, MY and NY3, two nearly insoluble salts, have the same Ksp values of 6.2 × 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. |
