|
Acid and base theory |
Acids and bases only show their properties when they are dissolved as salutes in water
Because acids and bases are ionic compounds they break down into separate ions each surrounded by water molecules
Breaking down of ionic compounds into separate ions = dissociation reaction |
|
|
Arrhenius acids and bases |
Acids form Aqueous solutions that contain H/hydroxide ions and a positivly charged ion (no OH/hydrogen ions)
Bases form aqueous solutions that contain hydrogen/OH ions and negatively charged ion (no H/hydroxide ions) |
|
|
Natural substances |
No H/hydroxide or OH/hydrogen ions in solution |
|
|
Bronsted Lowry theory |
Acid - substance loses a hydrogen ions Base - substance gains a hydrogen ion Conjugate acid - acid formed when a base accepts a hydrogen and the proton
Conjugate base - base formed when an acid loses a hydrogen ion and donates the proton/H+ |
|
|
Strengths of acids and bases |
Strong acids- highly dissociated, concentration of hydrogen ion will equal the concentration of the acid Weak acids- < 1% dissociation Storng base - concentration of hydroxide ion will equall the concentration of the base |
