NEETChemistryIonic Equilibrium
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  ) .
