Nitric Acid and Potassium Hydroxide Neutralization
HNO3 + KOH → KNO3 + H2O
概要
Nitric acid reacts with potassium hydroxide to produce potassium nitrate and water. This is a strong acid-strong base neutralization yielding a neutral salt. Potassium nitrate is one of the oldest known chemical compounds, historically called saltpeter.
