I think,
concentrated Nitric acid (HNO3)
HCL or H2SO4 will dissolve iron and not gold, platinum or palladium
the hydrochloric acid will dissolve the container and the acid will turn from green to brown
This depends on: - concentration of nitric acid - stirring - temperature - pressure - ratio iron/acid in the beaker - the physical form of iron: powder, granules, chips, etc.
Yup, hydrochloric, sulfuric (with hydrogen peroxide), and nitric acid should do the trick pretty quickly
Quartz will only dissolve in hydroflluoric acid.

Yes it will dissolve iron to produce Iron(II) sulfate and Hydrogen gas
the hydrochloric acid will dissolve the container and the acid will turn from green to brown
The acid rain can dissolve marble and is corrosive for iron railway lines.

Iron is a highly reactive metal and most of the strong acids like sulfuric acid and nitric acid are able to dissolve it. Steel is less reactive than iron because it is an alloy but will get corroded and dissolved in nitric acid solution 50-70 %. See also the link below.

16Mtric acid will dissolve copper, without heating.
I think that the point is: 1) if you have rust, then vinegar that contains acetic acids, will dissolve your rust 2) if the steel or iron doesn't have rust, then vinegar can rust the steel or iron 'cause it contains an acid. I means that acid will corrode steel or iron but even dissolve rust, that is an iron oxide.
An acid will dissolve something faster.
Oxalic acid can remove the rust due to its strong reducibility. The rust iron is ferric iron in the rusty spot, needless to dissolve into water. When touching oxalic acid, the ferric iron is reducted into bivalent iron which is dissolving in water. In addition, after using oxalic acid dihydrate to pickle ironmould on clothes, it is necessary to wash it with water a few times, not letting the excess of oxalic acid on clothes.
