Acid-An acid can be defined as an ion that forms an electron pair with a proton. The ph value of acid is 7 or less.
More easily we can understand that acid is capable of dissolving metal, can cause skin and clothes to burn. Mild Acid is used for cleaning purposes. Citric acid and ascorbic acid are commonly used acids present in lemon, orange etc.
Acids are of two types-
Strong Acid eg hydrochloric acid, nitric acid etc.
Weak Acid eg formic acid oxalic acid.
Bases-On the other hand bases when reacts with acid form a chemical bond. Metal oxide, Alkaoxide and hydroxide are some examples of bases.
Bases are of three types-
Strong base eg potassium hydroxide, sodium hydroxide.
Weak base eg ammonia, pyridine.
Superbase eg barium hydroxide.
Let us now summarize the differences in the table given below
|
Acid |
Base |
|
Forms electron pair with the help of the proton. |
Forms a chemical bond when mixed with acid. |
|
Arrhenius definition of an acid is that it is a compound that mixes with water to form an H+ ion. |
Arrhenius definition of base is that it is a watery substance that produces electrons. In this process (OH)- ions are released. |
|
Acid is a proton donor. |
The base is a proton acceptor. |
|
Stays colourless. |
Changes colour when dissolved with acid and turns pink. |
|
The Ph value is 7 or less. |
The Ph value is 7 or more. |
|
Acid changes litmus paper from blue to red. |
Changes red litmus paper to blue. |
