A buffer solution is prepared by mixing 20.0 mL 0.45 M CH3COOH (acetic acid) with 35.0 mL 0.45 M CH3COONa (sodium acetate) What is the amount of 4.0 M CH3COOH which must be added to this buffer solution to double the [H3O+]? What is the amount of 2.0 M HCl that must be added to decrease the pH by 0.50? How much NaOH(s) in g (grams) has to be added to the solution to raise the pH by 2.00?
