 In a double-replacement reaction, the _____.?


There are many more interesting things to ask about double replacement reactions than are contained in the list given here. But the only correct choice is: 

C.reactants are two ionic compounds

Answer: Option (c) is the correct answer.

Explanation:

A reaction in which there is exchange of two ions of two different compounds then this type of reaction is known as double-replacement reaction.

For example, [tex]Na_{2}S + 2HCl \rightarrow 2NaCl + H_{2}S[/tex]

Therefore, this results in the formation of two new ionic compounds whose properties are different from their reactants.

Thus, we can conclude that in a double-replacement reaction, the reactants are two ionic compounds.
