Bronsted-Lowry Model of acids and bases
Acids donate protons, while bases accept protons
Amphoteric substances
A substance that can act as both an acid and a base
Conjugate acids and bases
The compound formed in the products that is a result of the donation or acceptance of protons
Chemical buffer
A chemical system that resists a change in pH by maintaining equilibrium
Chemical buffers composition
Composed of conjugate acids/bases with a weak acid or base
Chemical bufferâs reaction to addition of hydrogen ions
The hydrogen ions will react with the anion and shift equilibrium to the opposite side. However, the concentration of hydrogen ions does not change, therefore pH does not change
Chemical bufferâs reaction to addition of hydroxide ions
The hydroxide ion will react with the cation and shift equilibrium to the opposite side of the reaction. However, the concentration of hydrogen ions does not change, therefore pH does not change
Acid buffer equation
H2O + HA ââ H3O+ + A-
Basic buffer equation
B + H2O ââ BH+ + OH-
Assumption for dissociation of weak acids and bases
Can assume less than 1% dissociation
