The correct Answer is:
To solve the problem of calculating the current required to produce 44 grams of \( \text{Hg}_2\text{Cl}_2 \) per hour through the electrolytic reduction of \( \text{Hg}^{2+} \) ions in the presence of \( \text{Cl}^- \) ions, we will follow these steps: ### Step 1: Calculate the equivalent weight of \( \text{Hg}_2\text{Cl}_2 \) The formula for equivalent weight is given by: \[ \text{Equivalent weight} = \frac{\text{Molar mass}}{\text{n}} \] where \( n \) is the number of electrons transferred per formula unit. 1. The molar mass of \( \text{Hg}_2\text{Cl}_2 \): - Atomic weight of \( \text{Hg} = 200.6 \) - Atomic weight of \( \text{Cl} = 35.5 \) - Molar mass of \( \text{Hg}_2\text{Cl}_2 = 2 \times 200.6 + 2 \times 35.5 = 401.2 + 71 = 472.2 \, \text{g/mol} \) 2. In the reaction \( 2 \text{Hg}^{2+} + 2 \text{Cl}^- + 2 e^- \rightarrow \text{Hg}_2\text{Cl}_2 \), 2 electrons are transferred. Thus, \( n = 2 \). 3. Therefore, the equivalent weight of \( \text{Hg}_2\text{Cl}_2 \): \[ \text{Equivalent weight} = \frac{472.2}{2} = 236.1 \, \text{g/equiv} \] ### Step 2: Use Faraday's law of electrolysis According to Faraday's law: \[ \frac{\text{Weight}}{\text{Equivalent weight}} = \frac{I \cdot t}{F} \] where: - \( I \) = current in amperes - \( t \) = time in seconds - \( F \) = Faraday's constant \( = 96500 \, \text{C/mol} \) ### Step 3: Convert time from hours to seconds Given that the production rate is 44 g per hour, we convert the time: \[ t = 1 \, \text{hour} = 3600 \, \text{seconds} \] ### Step 4: Substitute the values into Faraday's law We know: - Weight of \( \text{Hg}_2\text{Cl}_2 = 44 \, \text{g} \) - Equivalent weight = 236.1 g/equiv - Time = 3600 s - Faraday's constant = 96500 C/mol Substituting these values into the equation: \[ \frac{44}{236.1} = \frac{I \cdot 3600}{96500} \] ### Step 5: Solve for current \( I \) Rearranging the equation gives: \[ I = \frac{44 \cdot 96500}{236.1 \cdot 3600} \] Calculating the right-hand side: \[ I = \frac{4258000}{849960} \approx 5.01 \, \text{A} \] ### Conclusion Thus, the current required to produce 44 g of \( \text{Hg}_2\text{Cl}_2 \) per hour is approximately: \[ \boxed{5 \, \text{A}} \]
