Which of the following is an acid-base neutralization reaction

sn+2hf-> snf2+h2

c2h4+3o2-> 2co2+h2o

mgcl2+ca(oh)2-> mg(oh)2+cacl2

hno3+koh-> kno3+h2o

The right choice is "HNO₃ + KOH → KNO₃ + H₂O"

Explanation:

acid-base neutralization reaction is a reaction in which acid react with base to form salt and water.

This is a reaction between metal (Sn) and acid (HF)

    2. C₂H₄ + 3 O₂ → 2 CO₂ + H₂O

This is a combustion reaction

    3. MgCl₂ + Ca(OH)₂  →  Mg(OH)₂ + CaCl₂

This is a simple displacement reaction between salt (MgCl₂) and base (Ca(OH)₂).

    3. HNO₃ + KOH → KNO₃ + H₂O

This is a acid-base neutralization reaction in which acid (HNO₃) react with base (KOH) to form salt (KNO₃) and water (H₂O).

So, the right choice is "HNO₃ + KOH → KNO₃ + H₂O"
