Questions and Answers
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.
What impact does the addition of CH3COONa have on the dissociation of acetic acid?
What impact does the addition of CH3COONa have on the dissociation of acetic acid?
How does the addition of acetate ion affect the pH of the solution?
How does the addition of acetate ion affect the pH of the solution?
Adding CH3COONa to a solution of acetic acid decreases the concentration of H3O+ ions
Adding CH3COONa to a solution of acetic acid decreases the concentration of H3O+ ions
The addition of CH3COONa to a solution of acetic acid increases the % dissociation of the acid
The addition of CH3COONa to a solution of acetic acid increases the % dissociation of the acid
The equilibrium shifts to the right when CH3COONa is added to a solution of acetic acid
The equilibrium shifts to the right when CH3COONa is added to a solution of acetic acid
The pH of the acetic acid solution decreases as the concentration of added acetate ion increases
The pH of the acetic acid solution decreases as the concentration of added acetate ion increases
