WebThe reaction between sodium hydroxide and sulfuric acid is: 2NaOH + H2SO4 = Na2SO4 + 2H2O, which is a standard neutralization reaction. At 2-molar NaOH concentration, the amount of sulfuric acid (96%) which can be neutralized by 100 milliliters of alkali solution is approximately 10 grams. WebTreating graphite with strong acids in the presence of oxidizing agents causes the graphite to oxidise. Graphite bisulfate, [C 24] + [HSO 4] −, is prepared by this approach using sulfuric acid and a little nitric acid or chromic acid. The analogous graphite perchlorate can be made similarly by reaction with perchloric acid. [clarification needed]
