Acids, bases and salts MCQ — 1 Practice Questions with Answers

Explanation

When an acid reacts with a base, hydrogen ions from the acid and hydroxide ions from the base combine to form water, usually along with a salt. This is called a neutralization reaction because the acidic and basic properties are reduced. A catalytic reaction is defined by the presence of a catalyst that changes the rate of reaction. An addition reaction usually involves two species combining, commonly in organic chemistry. A dissociation reaction involves a compound splitting into ions or simpler species, so it does not name the acid-base reaction.
