The reaction represented when sodium chloride reacts with copper sulfate to produce sodium sulfate and copper chloride is a <u> double replacement reaction.</u>
<u><em> Explanation</em></u>
<u><em> A double replacement reaction </em></u> is type of chemical reaction where two compound react and a positive ions and negative ions of the two reactant switch places forming new compound.
The reaction of sodium chloride + Copper sulfate → sodium sulfate + copper chloride is a double replacement reaction because;
sodium since it is a more reactive metal than copper it replaces copper from it's compound which result to formation of new products( sodium sulfate and copper chloride)
