Question

Which equation represents neutralization?

6Li(s) + N2(g) → 2Li3N(S)
2Mg(s) + O2(g) → 2MgO(S)
2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)
Pb(NO3)2(aq) + K2CrO4(aq) → 2KNO3(aq) PbCrO4(s)

Answer 1

2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

Step-by-step explanation:

A neutralization reaction refers to any reaction between an acid and a base to form salt and water only. In a neutralization reaction, the key reaction that takes place to produce water is shown ionically below;

H^+(aq) +OH^-(aq) ----> H2O(l)

Looking at all the options provided, our gaze will have to settle on the reaction;

2KOH(aq) + H2SO4(aq) → K2SO4(aq) + 2H2O(l)

We can clearly see that there is an acid that reacts with a base to form a salt and water. The base contains the OH^- ion while the acid contains the hydrogen ion.

This is the only reaction of this sort among the options hence it is the correct answer.
