A formula for neutralization of H2SO4 by KOH is H2SO4(aq) + 2KOH(aq) --> K2SO4(aq) + 2H2O(l). This reaction between sulfuric acid and potassium hydroxide creates salt and water.
The formula H2SO4(aq) + 2KOH(aq) --> K2SO4(aq) + 2H2O(l) represents a neutralization reaction of the acidic sulfuric acid and the alkaline potassium hydroxide. When these two chemicals are mixed together, they create a solution of water, or H2O, and potassium sulfate, a salt. Sulfuric acid is a strong acid and potassium hydroxide is a strong base. The reaction that takes place is exothermic; this means that heat is a byproduct of the reaction.
