Question

How do i know which one to choose? please explain!

Answer 1

Neutralization is a reaction between an acid and a base to prduce a salt plus water.

A is a rx between 2 salts, ie double replacement (actually no rx)

B is a rx between an acid, HNO3 and a base KOH ie neutralization

C is a rx that results in formation of acid, ie synthesis

D is a synthesis rx, not neutralization

E is a decomposition rx, not neutralization

Answer is B
