WebApr 6, 2024 · So, let us refer the equation of chemical reaction of zinc and iron with dilute sulphuric acid- Z n + H 2 S O 4 → Z n S O 4 + H 2 F e + H 2 S O 4 → F e S O 4 + H 2 Now, … WebWhy one test tube is dilute sulphuric acid is required in permanganate titration? Add a test tube full of sulfuric acid in order to prevent oxidation of manganese to form manganese dioxide. Heat the mixture upto 60oC before titrating with potassium permanganate. Note down the initial reading in the burette before starting the titration.

WebConsider the redox reaction: $$\ce{2Fe^2+ + SO4^2- + 4H+ -> 2Fe^3+ + SO2 + 2H2O}$$ In the dilute acid, this equilibrium lies far to the left because the concentrations of $\ce{SO4^2-}$ and $\ce{H+}$ are rather low. However, making the acid more concentrated shifts the equilibrium to the right so that you get some of the products. my puppy swallowed a small rock
