Molecular Substances Are Made of Molecules, Share Electrons (Covalent Bond), Composed

Electrolytes

Electrolytes are substances that break up (dissociate or ionize) in water to produce ions. These ions are capable of conducting an electric current (electrolyte).

Remember…

¤  Molecular substances are made of molecules, share electrons (covalent bond), composed of nonmetals.

¤  Ionic substances are made of cations (+) and anions (-), transfer electrons, ionic substances are salts.

Classify the following compounds as a molecular substance or ionic substance, electrolyte or non-electrolyte, and write the dissociation equation.

Example

Compound / Molecular substance or ionic substance / Electrolyte or non-electrolyte / Dissociation equation
NaCl / Ionic substance / Electrolyte / NaCl (s) Na+1(aq) + Cl-1(aq)
Compound / Molecular substance or ionic substance / Electrolyte or non-electrolyte / Dissociation equation
Na2SO4
KOH
C6H12O6
Mg(OH)2
NaOH
K2CO3
