A 31.5 ml aliquot of H2SO4 of an unknown concentration was titration with 0.0134 M NaOH. write the balanced chemical reaction with the correct states of matter.

H2SO4(aq) + 2NaOH(aq) ==> Na2SO4(aq) + H2O(l).

To write a balanced chemical reaction with the correct states of matter, we need to determine the reactants and products involved in the titration between H2SO4 and NaOH.

The reaction between H2SO4 (sulfuric acid) and NaOH (sodium hydroxide) is an acid-base reaction. The balanced chemical equation is as follows:

H2SO4 (aq) + 2 NaOH (aq) ⟶ Na2SO4 (aq) + 2 H2O (l)

In this reaction, sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH) to produce sodium sulfate (Na2SO4) and water (H2O). The state of matter for sulfuric acid (H2SO4) and sodium hydroxide (NaOH) is aqueous (aq), indicating that they are dissolved in water. The state of matter for water (H2O) is liquid (l), indicating it is not dissolved or in a gaseous state. The state of matter for sodium sulfate (Na2SO4) is also aqueous (aq).

It is important to note that the coefficients in the balanced equation must be determined experimentally through the titration, as they represent the stoichiometry of the reaction.
