Why do ionic compounds dissolve well in water? Select all that are true.
Question 5 options:
Because water and ionic compounds are both polar | ||||||||||||||||||||||||||||||||||||||||||||
Water molecules have partial charges that attract the ions in the solid compound, causing it to dissociate into separated ions | ||||||||||||||||||||||||||||||||||||||||||||
Because organic compounds are nonpolar | ||||||||||||||||||||||||||||||||||||||||||||
Water molecules can surround an ion, and neutralize the ion's charge using either it's partial positive or negative side. | ||||||||||||||||||||||||||||||||||||||||||||
The individual ions are solvated by water molecules which stabilizes the ions 2. Which compound is soluble in ether but not soluble in aqueous sodium hydroxide? Question 2 options:
