Standard reduction potentials (SRP) for different systems can be used to decide the spontaneity of a reaction e.g., `E_(2n^(2+)//Zn)^(@)=-0.76V`, hence for the reaction `Zn+2H^(+)rarrZn^(2+)+H_(2),DeltaG^(@)` is negative. It has been found experimentally that if (SRP of an oxidant-SRP of a reductant) is more than 1.7V, then their combination may lead to explosion (though it may be prevented by kinetic factors).
Now go through the following data and answer the questions.
Data:
Which of the following ionic combinations may lead to the formation of explosive substance?
A. Sodium ion and azide ion
B. Silver ion and perchlorate ion
C. Silver ion and azide ion
D. All of the above
