Q.7. What are strong and weak acids. Write their uses.
Dear Student
A strong acid is an acid which ionizes almost completely when dissolved in water to produce a high concentration of hydrogen [H+]ions while a weak acid is an acid which ionizes partially when dissolved in water to produce a low concentration of hydrogen [H+] ions.
The strong acids are generally inorganic acids like HCl, H2SO4 , etc while the weak acids are generally organic acid with carboxylic acid (-COOH) groups as HCOOH (formic acid) , CH3COOH(acetic acid) etc.
Strong acid like H2SO4 is used in lead acid battery, while weak acid like CH3COOH is used as preservative.
