Basis	Acid	Base
Definition	An acid is any chemical compound once dissolved in water produces a solution with hydrogen ion activity more than purified water	A base is an aqueous substance that could absorb hydrogen ions.
Strength	Relies on the concentration of the hydronium ions	Relies on the concentration of the hydroxide ions
Examples	Acetic acid CH3COOH and sulphuric acid	Sodium Hydroxide (NaOH) and Ammonia
Characteristics (Physical)	Would depend upon the temperature acids would look solid, liquid or in the form of gas. It would also have a sour taste.	Bases would feel slippery and solid in nature (except for ammonia, which is gaseous). It would have a bitter taste.
Disassociation	Acids would release hydrogen ions (h+) when mixed with water	Bases would release hydroxide ions(OH-) when mixed with water
Test with Litmus	Would turn litmus paper red	Would turn litmus paper blue

Acid are the sour substances that turn blue litmus red and they have a lower ph value they give out H+ ions in water Whereas Bases are the substances that are bitter in taste they turn red litmus blue and they have high ph value they give out OH-ions in aqueous solution

Acid is sour in taste and Base is bitter to taste. Acid may cause burn but base feels soapy to touch.
