A volume of x m L of 5 M NaHCO 3 solution was mixed with 10 mL of 2 M H 2 C O 3 solution to make an electrolytic buffer.
If the same buffer was used in the following electrochemical cell to record a cell potential of 235.3 mV , then the value ofx = _ _ _ _ mL (nearest integer).
S n ( s ) | S n ( O H ) 6 2 − ( 0.5 M ) | H S n O 2 − ( 0.05 M ) | O H − | B i 2 O 3 ( s ) ∣ B i ( s )
