The chemical equation Zn(NO3)2 + KOH -> Zn(OH)2 + 2KNO3

  1. Detailed information about the equation Zn(NO3)2 + KOH -> Zn(OH)2 + 2KNO3:
  • 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).
  1. 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.
  1. 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.

  1. Observed phenomena:
  • When the reaction occurs, we will see the phenomenon of white zinc hydroxide precipitate (Zn(OH)2) appearing.
