Question

h₂so₄(aq) + koh(aq) → k₂so₄(aq)
which type of chemical reaction is represented above?
single replacement
combustion
neutralization
oxidation reduction

Explanation:

• Single replacement: In a single - replacement reaction, one element replaces another in a compound. The general form is \(A + BC

ightarrow AC + B\). Here, \(H_2SO_4\) (an acid) and \(KOH\) (a base) do not follow this pattern.

• Combustion: Combustion reactions involve a substance reacting with oxygen (usually in the form of \(O_2\)) to produce oxides and heat. There is no oxygen as a reactant in \(H_2SO_4(aq)+KOH(aq)\) reaction.
• Neutralization: Neutralization reactions occur between an acid (\(H_2SO_4\) is an acid, \(H^+\) donor) and a base (\(KOH\) is a base, \(OH^-\) donor). The general form of a neutralization reaction between \(H_2SO_4\) and \(KOH\) is \(H_2SO_4 + 2KOH=K_2SO_4+2H_2O\). The reaction \(H_2SO_4(aq)+KOH(aq)\to K_2SO_4(aq)+\) (water is also formed, though not fully written in the given equation) is a classic acid - base (neutralization) reaction.
• Oxidation - reduction: Oxidation - reduction reactions involve a transfer of electrons (change in oxidation states). In the reaction \(H_2SO_4 + KOH\), there is no change in the oxidation states of \(H\) (\(+ 1\)), \(S\) (\(+6\)), \(O\) (\(-2\)), and \(K\) (\(+1\)) from reactants to products.

Answer:

Neutralization
