What mass of aluminum metal can be produced per hour in the electrolysis of a molten aluminum salt by a current of 21 A ?two significant figures
Added by Robert R.
Step 1
In this case, we are dealing with the electrolysis of aluminum oxide (Al2O3) to produce aluminum metal. The half-reaction at the cathode (where reduction occurs) can be represented as: Al^3+ + 3e^- → Al. This tells us that 3 moles of electrons are required to Show more…

What mass of aluminum metal can be produced per hour in the electrolysis of a molten aluminum salt by a current of 25 $\mathrm{A}$ ?
Aluminum is produced commercially by the electrolysis of $\mathrm{Al}_{2} \mathrm{O}_{3}$ in the presence of a molten salt. If a plant has a continuous capacity of 1.00 $\mathrm{million} \mathrm{A}$ , what mass of aluminum can be produced in 2.00 $\mathrm{h}$ ?
