Question

Define the terms- acid and base.

Answer 1

Answer:

An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.

Answer 2

Answer:

• An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond .
• A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
• In short , Acid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper)
• And Base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions
