Question

Is double displacement reaction a redox reduction ? Explain How is it different from single displacement reaction?​

Answer 1

Answer:

A single replacement reaction “replaces” an element in the reactants with another element in the products.A double replacement reaction is similar to a single replacement reaction, but involves “replacing” two elements in the reactants with two in the products.

Explanation:

Mark as brainliest answer please.

Answer 2

Answer:

No, double displacement reaction are not a redox rection because there is no change of oxidation state of an element .

Explanation:

For it to be a redox reaction, elements have to change oxidation states and that does not happen in double replacement reactions.

E.g AgNO3+NaCl→AgCl+NaNO3

Ag is +1 before and after the reaction;

Na is +1 before and after the reaction too;

Both NO3 and Cl are -1 before and after the reaction;

Therefore, it is not a redox reaction.
