Ionic and Covalent Compounds (3)

The solubility of ionic compound in water

Most ionic compounds are soluble in water

The solubility of ionic compound in organic solvents

Most ionic compounds are not soluble in water

The solubility of covalent compound in water

Most covalent compounds are not soluble in water

The solubility of ionic compound in organic solvents

Most covalent compounds are soluble in organic solvents

Ions can move freely in water

When dissolved in water, water molecules help to overcome electrostatic attraction force between ions and break down the lattice structure of the solid compound

Lattice structure

Is the orderly arrangement of atoms, ions or molecules of a compound in a solid crystal

Situation that cause ionic compounds are not soluble in organic solvents

Organic solvents cannot overcome electrostatic forces between ions in a solid ionic compound

Situation that cause molecules in a covalent compound are soluble in an organic solvent but not soluble in water

Molecules in a covalent compound are neutral and do not carry any charges

The solubility of sodium chloride, NaCI in water (1)

Water is a polar solvent that has partial negative charge at the oxygen atom and partial positive charge at the hydrogen atom

The solubility of sodium chloride, NaCI in water (2)

Positive ion, Na+ will be attracted to the oxygen atom of water molecule which is negatively-charged
