HU NAU 4. For each beaker, calculate the expected (theoretical) pH when 5.00 mL of 0.0100 M HCI or 5.00 mL of 0.0100 M NaOH is added to 20.0 ml of buffered and non-buffered systems. Use the actual volume of acid/base added in the calculation. Organize your answer in a table as shown below. Total 25mL MIV M2V 2 = (0,000) (5) = 25M₂ Actual volume of acid or base Measured pH Calculated (Theoretical) % error pH M₂ -103 (M²) added (ml.) 0.1M NaCl + acid (beaker 1) 5 1.40 0.1M NaCl + base (beaker 2) 5 11.90 Buffer+acid (beaker 3) 5 3.04 Buffer+base (beaker 4) 5 4.47 Buffer HC₂HO₂, Na Cz Hz O₂
