A buffer was prepared by mixing 100.0 mL 0.500 M of the acid (shown on the left) with 50.0 mL 0.500 M of the salt shown on the right. After preparation, a 10.0 mL aliquot is tested for its buffer capacity by adding 10.0 mL of 0.050 M HCI solution. What is the resulting pH of the aliquot with the added acid? Write answer in 3 significant figures.
