Predict the products of each of these reactions and write balanced complete ionic and net ionic equations for each. If no reaction occurs, write NOREACTION . H2SO4(aq)+Li2SO3(aq)→
You can start to consider this as a straightforward double
decomposition reaction:
H2SO4(aq) + Li2SO3(aq) → H2SO3(aq) + Li2SO4(aq)
But this cannot be a reaction because all products are (aq) as well
as all reactants are (aq) , At this point check on the requirements
for a double decomposition reaction. You will find that this does
not comply with these requirements.
What happens in reality is that the "compound" H2SO3 breaks down to
produce H2O and SO2
Now you can write a reaction equation:
H2SO4(aq) + Li2SO3(aq) → Li2SO4(aq) + SO2(g) + H2O(l)
Then the ionic equation is:
2H+(aq) + SO4 2-(aq) + 2Li+(aq) + SO3 2-(aq) → 2Li+(aq) + SO4
2-(aq) + SO2(g) + H2O(l)
And the net ionic equation is:
2H+(aq) + SO3 2-(aq) → SO2(g) + H2O(l)
