which type of reaction happens when a base is mixed with an acid?\no metal - base reaction\no neutralization…

Brief Explanations:

When an acid and a base react, they form a salt and water. This is called a neutralization reaction as the acidic and basic properties are neutralized. A metal - base reaction involves a metal and a base, a combustion reaction involves a substance reacting with oxygen and releasing heat and light, and a spontaneous reaction occurs without external influence. But the reaction between an acid and a base is a neutralization reaction.

Answer:

neutralization reaction
