You are watching: Would silver react with dilute sulfuric acid

That is interesting due to the fact that Hydrochloric Acid and Zinc provide off hydrogen and also Zinc Chloride.Thus I have actually assumed Sulfuric Acid and Zinc offered off hydrogen and Zinc Sulfate. Yet you space saying no Hydrogen is produced when using Silver and also Sulfuric mountain at a high temp.Interesting

If you look at the activity series of metals, you'll view that silver is towards the bottom of the list. It is no able to minimize the hydrogen ion in a sulfuric acid equipment to hydrogen gas, and thus become oxidized come the Ag+ ion. It's only at a high temperature that the strong oxidation powers of concentrated sulfuric acid is able come oxidize the silver metal. If friend take focused hydrochloric acid and heat it up and also throw part silver in there, naught will happen as hydrochloric acid is not virtually as strong an oxidizer together sulfuric acid is. With nitric acid, it's such a solid oxidizer the you don't even need to be in ~ elevated temperatures to dissolve silver.
But you room saying no Hydrogen is created when using Silver and Sulfuric acid at a high temp.InterestingI did not say this. I just said the silver and sulfuric acid might react.From reaction you deserve to see above, this is due to a palliation of sulfuric acid perform SO2.Other steels can likewise react in this method eg copper.In some situations oxidiser can be external - zb O2 native air. In these situations Pb or Pd deserve to be dissolved in water equipment of acetic acid and Au or Ag in diluted KCN
AWK--the reaction you posted is not balanced. Hmx9123, you are rather right, sulfur dioxide is missing. I created it (in words) in my second posting.
in this reaction , H2SO4 acts together an oxidizing certified dealer , no an mountain . Acid and metal will type H2 yet redox reaction wont form H2
I recognize that dipping silver right into HCl will turn blackeshI was wondering if the very same happens with H2SO4What would occur with acetic acid?Could you acquire a great production that H2 and O2 making use of silver as an electrode in electrolysis that H2O v a few drops that vinegar?Regards,Bill
