Sulfuric Acid Production - Fertiliser

[moekamo]

another sulfuric acid question....

whats a reaction where sulfuric acid is an oxidising agent

thanks

conc sulfuric acid oxidises a number of non metal species such as carbon, sulfur and phosphorus
eg.
S_(S) + 2H₂SO_4(l) ---> 3SO_(g) + 2H₂0_(l)

[StringFever]

Oxidising agent = oxidant = sulphuric acid undergoes reduction.

This means that the S in H2SO4 must be reduced from +6 to a lower oxidation number.

An example where this happens is:

Mg (s) + 2H2SO4(aq) --> MgSO4(aq) + SO2 + 2H2O

Where +6 in H2SO4 goes to +4 in SO2

Sulfuric acid can be reduced to three different species depending on various conditions and stoichiometric abundance of other reactants.

Sulfate --> Sulfur dioxide, elemental sulfur, hydrogen sulfide

Damn, why didn't I ask you to be my Chem tutor this year?! I want that Chem knowledge!

depending on what you are fissioning.

fission of hydrogen (or very light nucleus) is highly exothermic, but the activation energy is ridiculous (as you mentioned, >100million degrees)

fission of heavy elements (such as Uranium) is highly endothermic.

fission of uranium is endo? what about nuclear power plants

A reaction you could use in exam for sulfuric acid being used to produce fertiliser

Ca3(PO4)2 (s) + 2H2SO4 (l) + 4H2O(l) ---> Ca(H2PO4)2 (s) + 2CaSO4.2H2O (s) (superphosphate)

Way too complicated XD
I would just stick to the ammoniumm sulfate one

lol i agreee

[TheJosh]

yeah but i already memorised this until i found out about the ammonium sulfate one

so i just stick with this to the end

massive oops, got the words confused again. I've corrected that in the post.

me 2. wish i knew about ammonium sulphate one right in the beginning. lol. oh well...
