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.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
