6) When the reversible reaction HC;H;O2 (aq) E→ H*(aq) + C¿H3O;'(aq) is at equilibrium at room temperature, pH of the reaction mixture is 5. What will be the change in pH when you add a large amount of solid acetate (C;H;O;Na) to the reaction mixture? a) pH will not change because C;H;O;Na is not a part of the reaction equation. b) pH will not change because acetic acid and sodium acetate form a buffer c) pH will decrease because the reaction will shift towards reactants d) pH will increase because the reaction will shift towards reactants

Question
6) When the reversible reaction HC;H;O2 (aq) E> H*(aq) + C2H3O2(aq) is at equilibrium at room
temperature, pH of the reaction mixture is 5.
What will be the change in pH when you add a large amount of solid acetate (C2H30,Na) to the
reaction mixture?
a) pH will not change because C2H;O,Na is not a part of the reaction equation.
b) pH will not change because acetic acid and sodium acetate form a buffer
c) pH will decrease because the reaction will shift towards reactants
d) pH will increase because the reaction will shift towards reactants

Expert Solution
Step 1

The given chemical reaction in equilibrium is:

HC2H3O2(aq)  <------> H+(aq) + C2H3O2-(aq) ; pH = 5

Now we are adding sodium acetate (C2H3O2Na) to the above reaction in equilibrium.
