Q1)
Which of the following reactions is not a redox reaction?
NH4Cl + KOH → NH3+ H2O +KCl
2Rb + H2O → 2RbOH + H2
Zn + 2AgCN → 2Ag + Zn(CN)2
2CuI2→ 2CuI + I2
Ans :
NH4Cl + KOH → NH3+ H2O +KCl
In the reaction, no element is going to reduce and oxidise, hence it is not a redox reaction.
but in (A) hydrogen is getting oxidised and potassium is reduced.
