How Is the Sulfuric Acid and Sodium Hydroxide Neutralization Written?
The chemical equation for the neutralization of sulfuric acid and sodium hydroxide can be written as H2SO4 + 2NaOH —> 2H2O + 2NaSO4. The equation shows that sulfuric acid has an equivalent value of 2, which means that one molecule of H2SO4 can neutralize 2 molecules of a base, such as sodium hydroxide, which has an equivalent value of 1. The neutralization equation also represents one of the production processes that produces sodium sulfate, the sodium salt of sulfuric acid and is used to neutralize surplus sulfuric acid by sodium hydroxide during the making of rayon.
Neutralization reactions between acids and bases will produce H2O and a salt. The combination of the H+ and OH– ions generates the water found on the right-hand side of the equation.
