Sulfuric Acid and Potassium Hydroxide
H2SO4 + 2KOH → K2SO4 + 2H2O
ภาพรวม
Sulfuric acid reacts with potassium hydroxide to form potassium sulfate and water. This diprotic neutralization requires two equivalents of base. Potassium sulfate is a premium fertilizer providing both potassium and sulfur without chloride.
