The balanced neutralization equation for the reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH) in aqueous solution is:
H2SO4 + 2 KOH → K2SO4 + 2 H2O
In this reaction, one molecule of sulfuric acid reacts with two molecules of potassium hydroxide to produce one molecule of potassium sulfate and two molecules of water. This is a typical acid-base reaction, where H+ ions from the acid react with OH– ions from the base to form water. The leftover ions combine to form the salt, potassium sulfate.
