true or false? bacl₂(aq) + na₂so₄(aq) → baso₄(s) + 2 nacl(aq) is a redox reaction.
true
false

Explanation:

Step1: Recall redox - reaction definition

A redox reaction involves a change in oxidation states of reactants.

Step2: Determine oxidation states

In $BaCl_2$, $Ba$ has an oxidation state of +2 and $Cl$ has - 1. In $Na_2SO_4$, $Na$ has +1 and $S$ has +6, $O$ has -2. In $BaSO_4$, $Ba$ is +2, $S$ is +6, $O$ is -2. In $NaCl$, $Na$ is +1 and $Cl$ is -1. No oxidation - state changes occur.

Answer:

False
