Sulfuric Acid and Potassium Hydroxide
H2SO4 + 2KOH → K2SO4 + 2H2O
Overview
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.

Everyday Example
Potassium sulfate fertilizer is preferred for chloride-sensitive crops like tobacco, citrus, potatoes, and grapes.
Industrial Importance
Over 7 million tonnes of potassium sulfate are produced annually, primarily for agriculture. It commands a premium over potassium chloride for sensitive crop applications.
