Which reaction represents the process of neutralization? Mg (s) + 2HCl (aq) MgCl 2 (aq) + H 2 (g) HCl (aq) + KOH (aq) KCl (aq) + H 2 O (l) C. Pb (NO 3) 2 (aq) + CaCl 2 (aq) Ca (NO 3) 2 (aq) + PbCl 2 (s) D. 2KClO 3 (s) 2KCl (s) + 3O 2 (g)

HCl (aq) + KOH (aq) - -> KCl (aq) + H2O (l)

Explanation:

A neutralization reaction is the process between an acid and a base (there are a number of different ways to define acids and bases). An acid is a compound, which dissolves in water by releasing H + ions, and a base is a compound, which dissolves in water by releasing OH - ions (by Arrhenius' definition, the simplest one). In this case, the neutralization reaction is the process between HCl (hydrochloric acid) - an acid, and KOH (potassium hydroxide) - a base.
