- The equation above represents the neutralization reaction of nitric acid (HNO3) by potassium hydroxide (KOH) to produce zinc hydroxide precipitate (Zn(OH)2) and potassium nitrate salt (KNO3).
- Reaction conditions:
- The reaction occurs when there is sufficient temperature and necessary pressure, specifically under standard conditions, temperature of 25 degrees Celsius and pressure of 1 atm.
- The reaction process:
-
The reaction begins when the nitric acid in zinc nitrate salt (Zn(NO3)2) is neutralized by potassium hydroxide base (KOH).
-
The result is the formation of zinc hydroxide precipitate (Zn(OH)2) and potassium nitrate salt (KNO3), both of which are insoluble in water.
- Observed phenomena:
- When the reaction occurs, we will see the phenomenon of white zinc hydroxide precipitate (Zn(OH)2) appearing.
