Chemical Bonding

Ionic Properties &Acids

A. Properties

Bond Structure

Forms a Crystal Lattice Most therefore are solids

Melting Point

The structure gives ionic solids very

high melting points

Solubility

Ionic solids easily dissolve in H2O

The dissolved particles in solution allow

it to be a good conductor of electricity

These solns. Are known as

Electrolytes

B. Acids

Acids

Compounds that form H+ in water.

Formulas usually begin with ‘H’.

Examples:

HCl – hydrochloric acid

HNO3 – nitric acid

H2SO4 – sulfuric acid

Anion Ending Acid Name

-ide hydro-(stem)-ic acid

-ate (stem)-ic acid

-ite (stem)-ous acid
