What happens when (Given balanced equation):
Nitric acid is added to Kl (aq)?
Advertisements
उत्तर
Nitric acid act as oxidizing agent and oxidizes iodide to iodine.
\[\ce{HNO3 + H2O -> H3O+ + NO^{-}_{3}}\]
\[\ce{KI -> I- + K+}\]
\[\ce{2I- ->[-2e-] I2}\]
\[\ce{2HNO3 + H2O + 2KI -> NO^{-}_{3} + I2 + 2KNO3 + H3O+}\]
