Question

5. Determine if a precipitation reaction occurs between aqueous silver nitrate and aqueous calcium chloride. If a

precipitation reaction takes place, write a balanced chemical equation, total ionic equation and net ionic
equation for the reaction. Identify any spectator ions.
a. Balanced chemical equation: (3 marks)
b. Total ionic equation: (2 marks)
C. Net ionic equation: (1 mark)
d. Spectator ions: (1 mark)

Answer 1

See Explanation

Step-by-step explanation:

a) In writing the balanced chemical reaction equation, the number of atoms of each element on the right hand side must be the same as the number of atoms of each element on the left hand side. The balanced reaction equation is;

2AgNO3(aq) + CaCl2(aq) ------> 2AgCl(s) + Ca(NO3)2(aq)

b) The total ionic equation shows all the ions present in the reaction system as follows;

2Ag^+(aq) + 2NO3^-(aq) + Ca^2+(aq) + 2Cl^-(aq) ---->2AgCl(s) + Ca^2+(aq) + 2NO3^-(aq)

c) The net ionic equation shows the ions that really participated in the reaction;

2Ag^+(aq) + 2Cl^-(aq) ---->2AgCl(s)

d) The spectator ions didn't undergo any change from left to right in the reaction equation. They include;

NO3^-(aq) and Ca^2+(aq)
