Question

Difference Between Acid and Base.

Answer 1

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

Answer 2

Acids	Bases
These are sour to taste	These are bitter to taste.
Acids are proton donors or electron acceptors	Bases are proton acceptors or electron donors
Acids have a pH value of < 7.	Bases have a pH value > 7.
Acids turn blue litmus red.	Bases do not change the colour of blue litmus.
Acids do not change the colour of red litmus	Bases turn red litmus blue
With china rose indicator, these give a dark pink colour.	Bases give green colour with china rose indicator.
Acids do not change the colour of the turmeric indicator.	Bases turn the colour of the turmeric indicator to red
