• 1 moles of ions

• 2 moles of ions

• 3 moles of ions

• 4 moles of ions

The separation of ions that occurs when an ionic compound dissolves is

• dissociation

• electronegativity

• spectation

They process in which ions are formed from molecules when they are dissolved in solution.

• dissociation

• ionization

• spetation

• electronegativity

What determines whether a polar molecule will bi ionized in a polar solvent?

• the attraction of the polar solvent is stronger than the covalent bond in the solute

• the attraction of the polar solvent is weaker than the covalent bond in the solute

• only non-polar molecules are ionized

• molecular compounds are never ionized

If an electrical current can run through a solution, it is said to contain
