Match the following? Species Conjugate acid ( a ) NH 3 ( i ) H 2 CO 3 ( b ) HCO 3 - ( ii ) H 3 O + ( c ) H 2 O ( iii ) NH 4 + ( d ) HSO 4 - ( iv ) H 2 SO 4
Options
- A( a →  iii  ),( b → i ),( c → ii ),( d →  iv  )
- B( a → i ),( b →  iii  ),( c → ii ),( d → iv )
- C( a →  iii  ),( b →  ii  ),( c → i ),( d → iv )
- D( a → iii ) , ( b → ii ) , ( c → iv ) , ( d → i )
Correct answer
A. ( a →  iii  ),( b → i ),( c → ii ),( d →  iv  )
Step-by-step solution
A base is the compound which accept the H + . The conjugate acid is formed by accepting the proton. NH 3 formed the conjugate acid as NH 4 + . HCO 3 - formed the conjugate acid as H 2 CO 3 . H 2 O formed the conjugate acid as H 3 O + . HSO 4 - formed the conjugate acid as H 2 SO 4 . Hence, the correct matches are ( a →  iii  ),( b → i ),( c → ii ),( d →  iv  ) .
