Chromic Acid - Hexavalent Chrome - Mare Island Murder

Chrome plating workers in China have regularly discharged concentrated chromic acid to open waterways, allowed chromic acid to poison wells and other drinking water supplies. Workers in the plating industry there have died, their families have been poisoned, and entire villages have had their health ruined by airborne and land discharges of Chromic Acid.

For Question 2) ,Chromic acid, is not a compound which readily exists either isolated or in ,water,. Stable ",chromic acid," generally only works as a mixture of chromate (or dichromate) salts and a strong ,acid, such as hydrochloric or sulfuric; and the strength of these ,chromic acid, solutions probably depends on the strength of the co-,acid, present.

It seems that lead is a great liner for sulfuric ,acid, based chemistry, as our ,chromic acid, was. This is because lead gets a coating of lead oxide much like iron gets a ferric oxide coating, or rust. Sulfuric ,acid, will not remove this lead oxide coating, which actually serves to protect the lead from leaching.

22/3/2021, · Chromic acid and it's derivatives can also be used to destroy hazardous chemical compounds, as it, neutralizes, them, to carbon ,dioxide and water. However, chromic acid will (violently) oxidize alcohols to their respective aldehydes or ketones, which cannot be oxidized further by the acid alone, which limits it's use in neutralizing many compounds.

Chromic acid is a strong oxidizing agent, so probably would, oxidize the cyanide to a cyanate which, is, far less hazardous, and is the first step in killing cyanide. This is why cyanide needs to be stored in another area from acids and needs to be marked on top of the drum as well as on the sides or painted with some otherwise never used color like purple.
