Calculation of Total Volume of Gas Produced:
- Given Data:
- Current (I) = 50 mA = 0.05 A
- Time (t) = 12 hours = 12 x 3600 s (1 hour = 3600 s)
- Faraday's constant (F) = 96500 C/mol
- Current Efficiency = 25%
- Molar mass of NaCl = 58.44 g/mol
- Step 1: Calculate the number of moles of electrons:
- Given Current (I) = 0.05 A, Time (t) = 12 x 3600 s
- Total charge (Q) = I x t = 0.05 A x 12 x 3600 s
- Number of moles of electrons = Total charge / Faraday's constant
- Step 2: Calculate the number of moles of NaCl decomposed:
- NaCl → Na+ + Cl-
- 2 moles of electrons are required to decompose 1 mole of NaCl
- Number of moles of NaCl decomposed = Number of moles of electrons / 2
- Step 3: Calculate the volume of gas produced at STP:
- 1 mole of any gas at STP occupies 22.4 L
- Convert moles of gas produced to volume at STP using the ideal gas law
- Step 4: Apply Current Efficiency:
- Total volume of gas produced = Volume of gas at STP x Current Efficiency
- Step 5: Calculate the final answer:
- Convert the volume from liters to milliliters (1 L = 1000 ml)
Therefore, the total volume of gas produced at standard state is approximately 125.44 ml.
This calculation takes into account the current passed, time of electrolysis, and the efficiency of the electrolysis process in producing gas from the electrolysis of NaCl solution.
