Answer:
ACIDS
Acids are those substances that release one or more H+ ions in aqueous solution. An acid is a substance that can donate a hydrogen ion (H+) to another substance in an aqueous solution. Acids have a pH of less than 7.0. Acids are Sour in taste. It gives a burning sensation when comes to contact with the skin. Acids are usually sticky in nature. Acids are mostly obtained from natural sources.
BASES
Those substances that accept the proton and donate electron are termed as the base. A substance capable of releasing one or more OH- ions in aqueous solution is termed as the base. The pH values corresponding to bases are always greater than 7. A base that completely ionizes in water and thus produces a large number of hydroxide ions (OH- ions) is called a Strong Base or Strong Alkali. E.g. Sodium Hydroxide and Potassium Hydroxide
