Question 1

Q1 Zinc nitrate reacts with aqueous ammonia (NH4OH) to form a salt and a base.  (i) Name the salt and the base. (ii) Describe the observations for the reaction. (iii) Write a chemical equation for the reaction (include state symbols). (iv) Write an ionic equation for the reaction.  


i)The Salt is Ammonium Nitrate. The Base is Zinc Hydroxide.


ii)A white precipitate is formed during the reaction.


iii)Zn(NO3)2(aq)  + 2NH4OH(aq) ---> 2NH4(NO3)(aq) + Zn(OH)2 (s)


iv)Normal Equation:Zn²⁺(NO3)-2(aq)  + 2NH4⁺ OH-(aq)--->2NH4

⁺

(NO3) ⁻(aq) + Zn(OH)2 (s)
Ionic Equation:Zn²⁺ (aq) + 2OH^- (aq) ---> Zn(OH)2 (s)
