Question

Identify the type of reaction which will based on the information provided about the reactants:
$Fe{Cl}_3\left(aq\right)+NaOH\left(aq\right)\to$

• A. Synthesis
• B. Decomposition
• C. Single Replacement
• D. Double Replacement
• E. Combustion

Answer 1

The correct option is D Double Replacement

In the above reaction iron displaces sodium, forms $Fe(OH{)}_3$ and sodium forms $NaCl$. Hence it is a double displacement reaction.

$FeC{l}_3\left(aq\right)+NaOH\to Fe(OH{)}_3+NaCl$
