Distinguish between strong acids and weak acids. Give two examples each.

Explanation

Strong acids: The acids which undergo complete ionisation when dissolved in water and furnish large concentration of `H^(+)` ions are called strong acids.
Examples: Strong acids
`HC1 rarr H^(+) + C1^(-)`
`H_(2)SO_(4) rarr 2H^(+) + SO_(4)^(-2)`
Weak acids: The acids which ionise partially and furnish less concentration of `H^(+)` ions are called weak acids. All organic acids are weak acids.
Examples: Weak acids
`CH_(3)COOH rarr CH_(3)COO^(-) + H^(+)" "H_(2)CO_(3) rarr 2H^(+) + CO_(3)^(-2)`
