CLEANING AND DESCALING STAINLESS STEELS

metal-rich near the base metal. Most oxygen-rich scale is readily soluble in common pickling acids, but the metal-rich scale may require acids aggressive to the base metal itself. For this reason, pickling is sometimes preceded by a preconditioning step, such as an alkaline salt bath, or scale removal by mechanical means, such as shot blasting.

Batteries - IUPAC | International Union of Pure and

Batteries are devices that store energy to later be converted into electricity using chemical reactions. During discharge of a battery, the anode undergoes an oxidation reaction, which produces electrons, and the hode undergoes a reduction reaction, which absorbs electrons. These processes, when organized in a device with an electrolyte and separator, produce electric current.

Does sulfuric acid react with copper? - Quora

In summary, sulfuric acid is not a strongly oxidizing acid, however, concentrated sulfuric acid is a strong enough oxidizing agent to dissolve copper. Sulfur dioxide is produced by reduction of the sulfuric acid. That copper(II) ions are in the aqueous solution is shown by the formation of the deep blue copper-ammonia complex.

Alkaline-earth Metals | Encyclopedia

2019-4-8 · Yet another similarity the alkaline earth metals have with the alkali metals is the fact that four of the them — magnesium, calcium, strontium, and barium — were either identified or isolated in the first decade of the nineteenth century by English chemist Sir Humphry Davy (1778-1829). Around the same time, Davy also isolated sodium and potassium from the alkali metal family.

What Is Lime Used for in Water Treatment? | Sciencing

"Hard" water contains dissolved mineral compounds, including calcium and magnesium, and the softening process removes them. It might seem counterintuitive to add calcium to water in order to remove calcium from water, but the process uses chemical reactions in a high-pH environment to form calcium compounds that precipitate into solids, which can then be filtered out.
