A buffer contains significant amounts of acetic acid and sodium acetate.
Write an equation showing how this buffer neutralizes added acid (HNO3 (aq).
Write an equation showing how this buffer neutralizes added base (KOH(aq)).
A)
HNO3(aq)+NaC₂H₃O2(aq)→HC₂H₃O2(aq)+NaNO3(aq)
B)
equation for buffer neutralization
KOH(aq) --> K+(aq) + OH-(aq)
there is OH-
so:
HC2H3O(aq) + OH-(aq) --> H2O(l) + C2H3O-(aq)

For a buffer made from sodium acetate and acetic acid, the Ka of acetic acid is 1.8E-5. What mass of sodium acetate (NaCH3CO2) must be added to 2.50 L of 0.68 M acetic acid to make a buffer solution with pH = 5.75? The answer should be in two significant figures.
A buffer solution contains 0.05 mol of acetic acid and 0.065 mol of sodium acetate in 1.00-L. What is the pH of the buffer after the addition of 0.01 mol of HNO3? Ka(acetic acid) = 1.8 x 10^-5 Thank you!
The acetic acid/acetate buffer system is a common buffer used in the laboratory. Write the equilibrium equation for the acetic acid/acetate buffer system. The formula of acetic acid is CH3CO2H. equilibrium equation: Which way does the equilibrium shift if more H3O+ is added? The equilibrium will not change. The equilibrium will shift to the left. The equilibrium will shift to the right. Which way does the equilibrium shift if more OH- is added? The equilibrium will shift to the right. The equilibrium will shift to the left. The equilibrium will...
