classification of acids on the basis of the strength
Answers
Answer:
acid can be classified according to its strength (degree of ionization) source and basicity acids are classified according to its degree of ionization in the aqua solution into strong acids and weak acid
source of acid
Apple ....malic acid
vinegar .....acetic acid
lemon..... nitric acid
milk .....lactic acid
Answer:
Acids produce hydrogen ions when mixed with H2O, the strength of an acid depends on its concentration of the hydrogen ions present in a solution. A greater number of hydrogen ions means greater strength of the acid whereas, lower number of hydrogen ions means that the acid is weak. They are classified as :
Strong Acids: An acid which can be dissociated completely or almost completely in water is known as a strong acid. For e.g. sulphuric acid, nitric acid, hydrochloric acid, etc.
H+ + H2O <—-> H3O
Weak Acids: An acid which doesn’t dissociate completely or dissociates negligibly in water is known as a weak acid. For e.g. Those that which we usually consume on daily basis i.e. citric acid, acetic acid, etc.
CH3COOH9(aq) <—–> CH3COO-(aq) + H2
