Problem: Would you expect NiO to dissolve in an aqueous solution of NaNO3?Figure Metal oxides reacts with acids. NiO does not dissolve in water but does react with nitric acid (HNO3) to give a green solution of Ni(NO3)2

FREE Expert Solution
  • Analyzing the reaction of HNO3 with NiO, it appears that the reaction is an acid base reaction since we produced water as product
  • Balanced reaction is:

NiO (s) + 2 HNO3 (aq) → Ni(NO3)2 (aq) + H2O (l)

  • If we further react NiO with NaNOin water, it will appear as:
