First, let’s write the reaction equation for these substances:
Ba (OH) 2 + H2SO4 = BaSO4 (precipitates) + 2H2O.
This reaction is feasible, as it results in a white curdled precipitate (BaSO4).
Let’s write the ionic equation of this reaction:
Ba (2+) + 2OH (-) + 2H (+) + SO4 (2-) = BaSO4 (precipitate) + 2H (+) + 2OH (-).
As a result, after abbreviations, we get an abbreviated ionic equation:
Ba (2+) + SO4 (2-) = BaSO4 (sediment).
