8.3: Electrochemistry- Cells and Batteries
The zinc can serves as both a container and the negative electrode. The positive electrode is a rod made of carbon that is surrounded by a paste of manganese(IV) oxide, zinc chloride, ammonium chloride, carbon powder, and a small amount of water. The reaction at the anode can be represented as the ordinary oxidation of zinc:

A Step-by-step Guide to the Zinc Electroplating Process
Step 1. Cleaning the Substrate. Cleaning of the substrate is done in order to remove any dirt, rust, oil, etc., from the surface. An alkaline detergent is used to clean the surface to ensure the zinc electroplating is of good quality, and the plating remains intact for a long period of time. Improper cleaning usually results in a variety of ...

Separation of zinc from gold
You shouldn't try to run the alloy thru nitric, the karat, .790k, is too high. You should inquart with some silver and bring the karat down to about 6k, .250k, then the nitric will work dissolving the silver & zinc, thus leaving a gold sponge of about 98% to 99% purity. Then run the sponges thru AR for a higher purity.

This is because the copper is more electronegative than the zinc. The cell potential for this reaction is +1.10, since copper is being reduced and zinc is being oxidized, and if you plug this into the free energy equation for a cell,ΔG= −n× F × EMF, you get ΔG= −2e-× (9.64 x 10^4 F) × (+1.10V) = -212 kJ.

9.3: The Dissolution Process
This process is called solvation and is illustrated in Figure 9.3.1 9.3. 1. When the solvent is water, the word hydration, rather than solvation, is used. Figure 9.3.1 9.3. 1: Solvation. When a solute dissolves, the individual particles of solute become surrounded by solvent particles. Eventually the particle detaches from the remaining …

Refining Gold: Remove Zinc by Distillation
About 90 per cent, of the zinc is removed in the first 2.5 hours and at a temperature not much exceeding 1,200° C. To remove the remaining zinc requires from 1.5 to 2.5 hours, and a somewhat higher temperature. It seems desirable to heat the material finally to about 1,300° C. in order to remove the last of the zinc.

In the froth floatation process, zinc sulphide and lead
NaCN forms a layer of zinc complex and deposits on the surface of ZnS while prevents it for the formation of froth while PbS forms a froth. Thus, by using depressants two sulphide ores can be separated. Therefore, ZnS and PbS can be separated by using depressant and adjusting the proportion of oil to water. Hence, the correct options are (B ...
