Question

A neutralization reaction occurs between sodium hydroxide and sulfurous acid. Complete the equation below for the neutralization reaction that ocurs during the titration

Answer 1

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

Step-by-step explanation:

When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):

NaOH + H₂SO₃ → H₂O + Na₂SO₃

To balance the sodiums:

2NaOH + H₂SO₃ → H₂O + Na₂SO₃

And the hydrogens:

2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃

And this is the complete reaction for this neutralization reaction.
