which reaction represents the process of neutralization?

1) Mg + 2HCl ---> MgCl2 + H2
2) HCl + KOH ---> KCl + H2O
3) Pb(NO3)2 + CaCl2 ---> Ca(NO3)2 + PbCl2
4) 2KClO3 ---> 2KCl + 3O2

The answer would be 2

HCL An acid and KOH an alkali neutralise each other to form a neutral salt and water

Hope that helps

Answer: 2) [tex]HCl+KOH\rightarrow KCl+H_2O[/tex]

Explanation:  When an acid reacts with the base then it undergoes neutralization to form a salt and water.

1) [tex]Mg+2HCl \rightarrow MgCl_2+H_2[/tex]: is an example of single replacement reaction as Mg replaces hydrogen from its salt solution.

2) [tex]HCl+KOH\rightarrow KC+H_2O[/tex] : is an example of neutralization where acid and base reacts to give salt and water.

3) [tex]Pb(NO_3)_2+CaCl_2\rightarrow Ca(NO_3)_2+PbCl_2[/tex]:  is an example of double displacement reaction in which exchange of ions take place.

4) [tex]2KClO_3\rightarrow 2KCl+3O_2[/tex]: is an example of decomposition where a single reactant decomposes to give two or more products.
