Question

Please explain how come this we do not use CH3CO2H +H20 <-> H30+ + CH3CO2-

OR CH3CO2H + OH-    -> H20 + CH3CO2-

and how come the H+ decrease while it is effect of adding a base to the solution.

2. A buffer UFFER . A buffer is made from acetic acid (HC2H O2) and sodium acetate (NaC2H ). 1. 5 moles of acetic acid and 2.5 moles of sodium acetate are add ionization constant (Ka) for acetic acid is 1.8 x 10 ed to enough water to make 1.5 liter of solution. The a) Write the equation for the ionization of acetic acid in water, an d using a stress-shift- equilibriu the solution. m arrow diagram, show how the buffer would minimize the effect of adding a base to Stress: Shift: Equilibrium b) Using the Henderson-Hasselbalch equation, find the pH ef this buffer solution.

Explanation / Answer

CH3CO2H +H20 <-> H30+ + CH3CO2-

suppose if we add base to this

base reacts with H+ present in the solution

H3O+  + OH-  ----------> 2H2O

so acid will consume by reacting with base resulting equilibrium will shift towards right to increase the H+ concentration to reattain the equilibrium
