Identify the type of reaction based on what type of chemistry is happening between the
compounds (3 points- 1 point each)
Write the complete balanced chemical equation (3 points- 1 point each reaction)
For the acid-base and precipitation reactions, write the balanced overall and net ionic equations.
(1 point each reaction)
For the redox reactions, identify the which species is being reduced and which is being oxidized.
(1 point each reaction)
a) Aluminum metal is added to a solution of cobalt (II) sulfate.
b) Calcium hydroxide reacts with nitric acid.
c) Aqueous ammonium phosphate is mixed with aqueous strontium hydroxide
Solution
Solution :-
a) Aluminum metal is added to a solution of cobalt (II) sulfate.
Balanced reaction equation is as follows
2Al(s) + 3CoSO4(aq) ---> Al2(SO4)3(aq) + 3Co(s)
It is redox reaction (single replacement)

2. Al is reducing agent and CoSO4 is oxidizing agent
Total ionic equation is as follows
2Al(s) + 3Co^2+(aq) + 3SO4^2-(aq) ---> 2Al^3+(aq) + 3SO4^2-(aq) + 3Co(s)
Net ionic equation is as follows
2Al(s) + 3Co^2+(aq) ---> 2Al^3+(aq) + 3Co(s)
b) Calcium hydroxide reacts with nitric acid.
Balanced reaction equation is as follows
Ca(OH)2(aq) + 2HNO3(aq) ---> Ca(NO3)2(aq) + 2H2O(l)
This is acid base reaction (double replacment )
Total ionic equation is as follows
Ca^2+(aq) + 2OH^-(aq) + 2H^+(aq) + 2NO3^-(aq) ---> Ca^2+(aq) + 2NO3^-(aq) + 2H2O(l)
Net ionic equation is as follows
2OH^-(aq) + 2H^+(aq) ---> 2H2O(l)
c) Aqueous ammonium phosphate is mixed with aqueous strontium hydroxide
Balanced reaction equation is as follows
2(NH4)3PO4(aq) + 3Sr(OH)2(aq) ----> Sr3(PO4)2(s) + 6NH4OH(aq)
This is precipitation reaction (double replacement )
Total ionic equation is as follows
