Prepare for EYE : 5 Questions on Ionic Equations, Colours of Cations & Anions, Acids, Bases, Alkalis, Salts

Q1.(i) Zinc Nitrate+Aqueous ammonia --> Zinc hydroxide + Ammonium Nitrate
Thus, the salt formed is ammonium nitrate while the base for is zinc hydroxide.

(ii) Observation of reaction: When Ammonium hydroxide(colourless solution) is added to Zinc nitrate(also colourless solution), white precipitates formed as Zinc Hydroxide is insoluble.

(iii)   Zn(NO3)2 (aq) + 2NH4OH (aq) --> Zn(OH)2 (s)+ 2NH4NO3 (aq)

 (iv)
