Problem: Which produces the greatest numbers of ions when one mole dissolves in water?a. LiCl b. NH4I c. NaMnO4 d. CO2 e. K2CO3

FREE Expert Solution

We're being asked to determine which compound produces the greatest numbers of ions when one mole dissolves in water.

Covalent or Molecular Compound

▪ composed of more than one nonmetal together
▪ nonmetal + nonmetal = covalent bond

Ionic Compound

▪ composed of a positive ion called a cation connected to a negative ion called an anion.
positive ions (cations) are usually metals and negative ions (anion) are usually nonmetals

metal + nonmetal = ionic bond

▪ cations and anions can also be polyatomic ions (example: NH4+, C­H3COO-, SO42-)
