Conjugate acid- compound formed when an base gains a hydrogen ion.
Conjugate base – compound formed when an acid loses a hydrogen ion.
pH of Common Substances

Reactions with indicators
pH paper changes color to indicate a specific pH value.
A buffer is a solution that resists changes in pH when small amounts of acids and bases are added.
Planting vegetables and flowers
Fish Tanks and Ponds
HCl + H20 H3O + + Cl- (more hydronium ions, more acidic)
NaOH in water Na+ + OH- (more hydroxide ions, more basic)
NaOH + HCl NaCl + HOH Acid + Base yields type of salt and water
NH3 + H20 NH4+ + OH- ammonia gas + water yields ammonium and hydroxide ions
Pollution in the air (sulfur dioxide, carbon dioxide, nitrogen dioxide) combines with water to form various acids.
Rapid changes in pH can kill fish and other organisms in lakes and streams.
Soil pH is affected and can kill plants and create sinkholes
A salt is a neutral substance produced from the reaction of an acid and a base.
Composed of the negative ion of an acid and the positive ion of a base.
One of the products of a Neutralization Reaction
Examples: KCl, MgSO4, Na3PO4
A neutralization reaction is the reaction of an acid with a base to produce salt and water.
