Sulfuric Acid: The molar mass of sulfuric acid is about 98 g/mol. It will not just boil, it will explode. 2. lye. This is because both the reactions are between a strong monoprotic acid and a strong alkali. . 4. 4th, 2022 Experimental . Neutralization of sulfuric acid (H2SO4) by sodium hydroxide (NaOH)proceeds in two steps as shown below. Pour a 1.0 molar solution of sulfuric acid into an insulated container. Sulfuric acid reacts with water to yield hydrogen sulfate ions and hydronium ions: H2SO4=H2O>HSO-4+H3O+. Sulfuric acid is used almost universally for neutralization reactions. Chemical equation Harman PGA coach . This is because both the reactions are between a strong monoprotic acid and a strong alkali. . The equation shows that sulfuric acid has an equivalent value of 2, which means that one molecule of H 2 SO 4 can neutralize 2 molecules of a base, such as sodium hydroxide, which has an equivalent value of 1. b.

The chemical equation for the neutralization of sulfuric acid and sodium hydroxide can be written as H2SO4 + 2NaOH —> 2H2O + 2NaSO4. Salts are ionic compounds formed from the neutralization of an acid and a base. Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H 2 SO 4.It is a colorless, odorless and viscous liquid that is miscible with water.. Once all the neutralized acid is disposed of, run lots of water down the drain for at least five minutes. Since there is no hydroxide ions we can not write water as a product. It is an acid -base neutralization reaction between a strong acid and a strong base. Neutralization is the basis of titration, where a pH indicator shows equivalence point when the equivalent number of moles of a base have been added to an acid. The acid then can be taken beyond a neutral pH of 7 by adding compounds such as sodium carbonate or sodium hydroxide that can raise its base . There are several different approaches available to neutralize sulfuric acid — H 2 SO 4 — depending on how precisely the process needs to be controlled and how the end product is to be handled.
