1. Determine the chemical reaction equation of electrolytic zinc: The chemical reaction equation of electrolytic zinc is: Zn2++2e- → Zn. According to this equation, we can know that for every two electrons released, 1 zinc ion can be obtained.

2. Determine the current intensity (i) and time (t) in the electrolytic cell: According to the reaction equation of electrolytic zinc, the required number of zinc ions can be determined. The current intensity and time can provide the total charge in the electrolyzer, that is, q = i× t.

3. Calculate the output of electrolytic zinc: According to the ratio of 1 zinc ion for every two electrons released, the calculated amount of zinc ions can be converted into mass by the molar mass of zinc ions. The calculation formula is the number of zinc ions (mol)= Q/(2×F), where q is the total charge passing through the electrolytic cell and f is Faraday constant.

4. Multiply the molar mass of zinc ions by the number of zinc ions to obtain the output of electrolytic zinc.

It should be noted that the output of electrolytic zinc in actual production may be affected by some factors, such as current efficiency and operating conditions in the electrolytic cell, which may lead to a certain deviation between the actual output and the theoretical calculation value.
