Which compound could serve as a reactant in a neutralization reaction?(1) NaCl (3) CH3OH(2) KOH (4) CH3CHO
Answer: (2) \(KOH\)
Explanation: When an acid reacts with the base then it undergoes neutralization to form a salt and water.
An acid is a substance that ionizes in the water to give hydrogen ion and have pH less than 7.
\(HX\rightarrow H^++X^-\)
A base is a substance that ionizes in the water to give hydroxide ion and has pH more than 7.
\(MOH\rightarrow M^++OH^-\)
Thus \(KOH\) being a base can be a reactant in neutralization reaction.
\(NaCl\) being a salt can be a product in a neutralization reaction.
