Indicate in each reaction which one is oxidised or reduced if any:

$C u S O_{4} + 4 K I \to 2 C u I + I_{2} + 2 K_{2} S O_{4}$

In the above reaction, which one of the following is oxidised?

Question

Indicate in each reaction which one is oxidised or reduced any-CuSO-4 - 4KI rightarrow 2CuI - I-2 - 2K-2SO-4In the above reaction- which one of the following is oxidised-CuSO-4I-2KINone of these

Toppr Admin · Accepted Answer

The balanced chemical equation is CuSO4-4KI-x2192-2CuI-I2-2K2SO4-The oxidation number of copper changes from -2 to -1-Thus- copper is reduced as its oxidation number decreases-The oxidation number of iodine changes from -1 to 0-Thus- iodine is oxidized as its oxidation number increases-

Indicate in each reaction which one is oxidised or reduced if any:CuSO4+4KI→2CuI+I2+2K2SO4In the above reaction, which one of the following is oxidised?CuSO4I2KINone of these

The balanced chemical equation is CuSO4+4KI→2CuI+I2+2K2SO4.The oxidation number of copper changes from +2 to +1.Thus, copper is reduced as its oxidation number decreases.The oxidation number of iodine changes from -1 to 0.Thus, iodine is oxidized as its oxidation number increases.
