Question
Please Help in writing this net ionic equation!
In sediments and waterlogged soil, dissolved O2 concentrations are so low that the microorganisms living there must rely on other sources of oxygen for respiration. Some bacteria can extract the oxygen in sulfate ions, reducing the sulfur in them to hydrogen sulfide gas and giving the sediments or soil a distinctive rotten-egg odor. a. What is the oxidation number of sulfur in these compounds? S02-(aq): Hydrogen is an element that most often forms a 1 ion while oxygen is an element that most often forms a -2 ion. What would these common ions imply about the sulfur ion's charge in the compound. H2S(g):-2 b. Write the net ionic equation for the reaction under acidic conditions (H30) that releases O2 from sulfate and forms hydrogen sulfide gas. Use water as the reactant in the half-reaction that describes the formation of oxygen. sol(aq) +6H + (aq) H,S(aq) + O2(g)+2H2O(1)Explanation / Answer
solution:
The balanced net ionic equation is
2SO42-(aq) + 8H+(aq) ---> 2H2S(g) + 2H2O(l) + 3O2(g)
