However, making the acid more concentrated shifts the equilibrium to the right so that you get some of the products. As to why you get a mixture of iron(II) and iron(III), the simple answer is that the equilibrium above doesn't lie entirely to the right. $\ce{H2SO4}$ is not that strong an oxidising agent to begin with.

When con­duct­ing chem­i­cal ex­per­i­ments, one must al­ways add sul­fu­ric acid to wa­ter, not the oth­er way around. Sul­fu­ric acid is a strong de­hy­drat­ing sub­stance, and con­cen­trat­ed sul­fu­ric acid forces wa­ter out of var­i­ous com­pounds. It is of­ten used as a dry­ing agent.

Sometimes the “language of science” should be precise, to avoid misunderstanding and “mis-answers”: there is no such thing as “the chemical equation for iron and sulphuric acid”! There is a chemical equation for THE REACTION BETWEEN IRON AND SULPHURIC ACID!

So an acid is defined in its ability to deliver an H+, or a proton. It does not mean all of the H+ is present in its ionized form. You have to add water for that to happen and the acid can then ...

en.wikipedia.org/wiki/Sulfuric_acid

Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO 4. It is a colorless, odorless, and syrupy liquid that is soluble in water, in a reaction that is highly exothermic.

Zinc sulfate doesn't react to give zinc hydroxide and sulfuric acid. It dissolves in water, forming Zn 2+ ions and sulfate ions, SO 4 2- . However, SO 4 2- is a weak base, and so it dissociates ...

The direct reaction between iron metal and iodine can be used to prepare iron (II) iodide, FeI 2. Fe(s) + I 2 (s) → FeI 2 (s) (grey) Reaction of iron with acids. Iron metal dissolves readily in dilute sulphuric acid in the absence of oxygen to form solutions containing the aquated Fe(II) ion together with hydrogen gas, H 2.

Sulphuric acid + iron (II) sulphate These corrosion data are mainly based on results of general corrosion laboratory tests , carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).

YES! Sulfuric acid's reaction with plastic can be treacherous. HDPE #2 will keep it contained for a long time (more than a few months by experience, probably years) but any HDPE #1 and any plastic ...

The effect of sulfuric acid on metal elements that are below hydrogen in the reactivity series is different, as they cannot displace hydrogen from the acid. These metals include copper, mercury, silver, gold and platinum. They will not react with dilute sulfuric acid, or with the concentrated acid at room temperature.
