What is linking electrons to product?Show answer
The electrode half-equation tells you how many electrons are needed per mole of product. The general routine is:
What are gas volumes?Show answer
If the product is a gas (for example at the anode, ), convert moles to volume using the molar gas volume at the stated conditions, or the ideal gas equation . The same electron bookkeeping applies; just watch the electrons per mole of gas, which is often more than for a metal.
