How does a buffer work through the common-ion effect?
How does a buffer work through the common-ion effect?
A buffer works through the common-ion effect by shifting the equilibrium to reduce the concentration of H3O+ ions, making the solution less acidic.
What is the effect of added acetate ion on the dissociation of acetic acid?
What is the effect of added acetate ion on the dissociation of acetic acid?
The added acetate ion reduces the % dissociation of acetic acid, making the solution less acidic and increasing the pH.
How is the % dissociation of acetic acid calculated?
How is the % dissociation of acetic acid calculated?
The % dissociation of acetic acid is calculated as the % dissociation = (% dissociation * CH3COOH dissociation) / CH3COOH initial concentration * 100.
