Question

1) Write a balanced net ionic equation for the reaction of AgNO3(aq) with KI(aq)

a)AgNO3(aq) + KI(aq) AgI(s) + KNO3(aq)

b)Ag+(aq) + I-(aq) AgI(s)

c)Ag+(aq) + NO3-(aq) + K+(aq) + I-(aq) AgI(s) + K+(aq) + NO3-(aq)

d)Ag+(aq) + NO3-(aq) + K+(aq) + I-(aq) AgI(s)

In the following reaction, what is the chemical role of I2?

2Cs(s) + I2 2CsI(s)

a)Acts as the reducing agent

b) Acts as the oxidizing agent

c)is oxidized

d)both b and c are correct

c)is oxidized

d)both b and c are correct

Q1.

AgNo3 + KI = Ag+ and I- will form AgI(s) and K+ and NO3- remain in solution

net ionic... is only those ions which precipitate

Ag+(aq) + I-(aq) --> AgI(s)

Q2.

chemical role of I2...

I goes from 0 to -1

so, it gains 1 electron, meaning it is reducing, therefore it is acting as oxidizing agnet

only B is true
