Question

What is the difference between an acid and a base?​

Answer 1

Answer:

Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.

Explanation:

An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). 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.

Answer 2

Answer:

• Acid is a kind of chemical compound that when dissolved in water gives a solution with H+ ion activity more than purified water.
• A base is an aqueous substance that donates electrons, accept protons or release hydroxide (OH-) ions.

• An acid is a proton donor.
• While a base is a proton acceptor.
