Making Descaling Liquid With Salt Electrolysis Process

This is an experiment to make descaling liquid by electrolyzing NaCl salt. In theory, if a solution of NaCl salt in water is then electrolyzed, new compounds will form, including NaOCl, which has the property of being able to clean all kinds of adhering dirt. But in this solution not only NaOCl is formed, but other compounds such as NaOH and Cl2 gas are formed.

Can this liquid clean the stubborn pan crust. This needs to be proven, for that I conducted an experiment by electrolyzing the NaCl salt solution. From this experiment, the salt solution, which was clear before, turned green in time. I suspect that this is a reaction with the large amount that was also dissolved in the salt solution. Now, whether the results of the electrolysis can be used for cleaning, you can check in the following video:

Electrochemical Process To Remove Iron Corrosion

As we know iron is a metal that is easily corroded in the open air. The iron will be brown due to the corrosion of the iron surface. If this is allowed then this corrosion will spread to the deeper layers of the iron.

The continuation of this corrosion must be prevented because if left unchecked, the iron will be consumed by corrosion.

In everyday life, there are various ways to prevent corrosion, including painting or smearing the surface of iron with oil, or blackenning before storing goods made of iron in a warehouse.

On the surface of the iron in general will experience corrosion in the open air so that on the surface of the iron will form an oxide layer, namely iron oxide.

In large iron goods industries that will undergo further processing, the oxide layer must be removed. Of course, the method is not done manually but using an electrochemical process.

This electrochemical rust removal process is basically having a metal object treated as the negative electrode while another object that is normally rust resistant is treated as the positive electrode. Then the two objects are put into a chemical solution and electrified. With this process, the oxide layer on the iron surface will decay and the iron will become clean.

To see this process, see my video below:

Nickel Plating

Nickel is one of the most important metals applied by electrodeposition. The plate is used principally as a bright coating underneath a much thinner chromium electroplate to provide a highly lustrous and corrosion-protective finish for articles of steel, brass, zinc die castings, chemically metallized plastics, and, to a much smaller extent, for coatings on aluminum alloy and magnesium alloys. The protection of the underlying metal depends primarily on the nickel plate, with the thin chromium overlay conferring a permanently nontarnishing, hard, wear-resistant surface. To a far lesser extent, and only for mild exposures, thin gold or brass electroplate with a clear lacquer finish is used as a decorative coating on thin bright nickel deposits. Nickel coating alone are also used industrially to afford corrosion protection to prevent contamination of a product. Because of favorable mechanical properties, nickel electrodeposits are used for electroforming of printing plates, phonographs record stampers’, foil and tubes, screens, and many other articles.


The history of the electrodeposition of nickel goes back more than 125 years. It began in 1843 that describe the first apparently sound nickel plate, which obtained from a bath containing nickel and ammonium sulfates. The first do nickel plating on a truly commercial basis used double salt baths, including both sulfate and chloride, and was probably the first to recognize the importance of impurities in the plating bath. He employed cast soluble anode which contained silicon, iron, and carbon. The only early developments that have survived, however, are Weston’s introduction of boric acid into the bath, the use of chlorides and promote anode corrosion, and the discovery about 1912, that cadmium salt act as brighteners. Electrolytic nickel refining profited by the experience of the nickel platter and has made use of warm nickel sulfate-boric acid solution since 1894.

Chromium Alloy Plating

Chromium alloy plating can be considered a subheading under trivalent bath, there is almost no alloy plating possible from hexavalent chromium solutions. There has been a great deal work, and some reviews are available, but nothing of commercial importance seems to have been developed. It appears likely that some fundamental problems of depositing chromium from trivalent baths remain to be solved, and that these are probably not made appreciably easier by introducing the added factor of alloy deposition. Alloy steel is one of good material as base plating metal for chromium electroplating.





One exception to the rule of no alloy plating from chromic acid baths is the work of Vagramyan and his collaborators. Alloys of up to 37% selenium, 15% manganese, 2% molybdenum, and 1 % rhenium were obtained with cold chromium deposits at about 20oC. These alloys are on the whole no longer obtained as the temperature is raised, so presumably they are alloys with the dull hexagonal hydride produced at low temperatures, and not with the bee deposits which form ordinary bright plate.

Much work has been done, mainly in France, to investigate claims of improved wear resistance of chromium-molybdenum alloys produced from chromic acid solutions. It appears that bright deposits generally contain less than 1% molybdenum, and this could possibly result from solution contamination of the deposit instead of alloying. Hard chromium plating baths are frequently a little low in catalyst due to too strict adherence to the 100:1 ratio of chromic acid to sulfate, and the improved wear resistance of deposits from solutions containing molybdenum compounds might be due to an effect on the catalyst balance of the solution.

Other Special Types of Chromium Plate

A "frosty" or satin-finish plate in between cold chromium and bright plate was found desirable for press plates. Such smooth-bubbly or natural rounded nodular plate has been found useful for handling textile materials. Some people used a special cold chromium plate produced in refrigerated electrolytes for printing plates. Black chrome plating can be obtained from immersing chromium deposits in molten cyanide acid.

The most important step on Electroplating is Preparation

The successful of electroplating process in on the preparation:

Preparation itself can involve on the object that will be treated into the metal plating, the chemical will use to process, the place of doing process and the source of electric to do this process.

Each of matter must be prepare accurately, any problem on the running process can effect to the final result of electroplating process. Preparation of basis metal should be done as the procedure to get perfect result, such as the metal use and the pretreatment to the basis metal before electroplating run.

For using new apparatus should be tested first before do a big project, small piece and many object forms can be tried by electroplating to make sure that the process of electroplating can result a perfect finish object.

Have a nice trial.
