Question

identify the type of reaction occurring based on the description below: \sodium hydroxide reacts with iron (iii) chloride.\ what type of reaction is this? a double - replacement b synthesis c decomposition d combustion reaction e single - replacement

Explanation:

In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. Sodium hydroxide (\(NaOH\)) is an ionic compound with \(Na^{+}\) and \(OH^{-}\) ions, and iron(III) chloride (\(FeCl_{3}\)) is an ionic compound with \(Fe^{3 +}\) and \(Cl^{-}\) ions. When they react, the \(Na^{+}\) and \(Fe^{3+}\) ions exchange their anions (\(OH^{-}\) and \(Cl^{-}\)). The general form of a double - replacement reaction is \(AB+CD
ightarrow AD + CB\). Here, \(AB = NaOH\), \(CD=FeCl_{3}\), \(AD = NaCl\) and \(CB=Fe(OH)_{3}\).

Answer:

A. Double - replacement
