A buffer is prepared by mixing 10.0 g of sodium bicarbonate,NaHCO3 (formula mass=84.01 g/mol) and 10.0 g of sodiumcarbonate, Na2CO3 (formula mass=106.0 g/mol)with sufficient water to make 250.0 mL of solution. 50.0-mL of this buffer solution is reacted with 50.0 mL of0.250 M HCl (aq). Calculate the pH of the mixture thatforms.
