14 State differences between acids and bases.
Answers
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.
Acids exist as solid, liquid, and gas-based on temperature. Bases usually exist in the solid-state except for ammonia which exists as a gas. Acids are sour in taste. Bases taste bitter.
