Carry out reactions between solutions of the following substances: Sodium hydroxide and sulfuric acid

Let’s write the reaction equation:
NaOH + H2SO4 = Na2SO4 + H2O
Let’s equalize the reaction by placing the coefficients. we get:
2NaOH + H2SO4 = Na2SO4 + 2H2O
This reaction belongs to exchange reactions, it proceeds to the end, since a little dissociable substance, water, has been formed.
An exchange reaction is such a reaction as a result of which complex substances exchange their constituent parts. It flows to the end, if a gas is formed, the substance precipitates out, or water is formed.
Let’s write the reaction in full and abbreviated ionic form.
2Na ^ (+) + 2OH ^ (-) + 2H ^ (+) + SO4 ^ (2-) = 2Na ^ (+) + SO4 ^ (2-) + 2H2O
Let us cancel similar terms on the right and left sides and get:
2OH ^ (-) + 2H ^ (+) = 2H2O
