HELP PLS A chemical reaction between an acid and a base that produces water and a salt is known as neutralization. Which of the following chemical equations represents a neutralization reaction?
NaCO3 (aq) + CuCl (aq) ® NaCl (aq) + CuCO3 (s)
HBr (aq) ® H+ (aq) + Br- (aq)
NH3 (aq) + HCl (aq) ® NH4Cl (aq)
HNO3 (aq) + KOH (aq) ® KNO3 (aq) + H2O (l)

Answer:

4th Option

Explanation:

HNO3 is an acid, KOH is a base and they react to produce KNO3 which is a salt and H2O water.

So this reaction is a neutralisation reaction.
