Limiting molar conductivity of NH ₄ OH~ ( i.e., _ m ( NH ₄ OH ) ) is equal to

Options

  1. A_ m ( NH ₄ Cl ) + _ m( NaCl ) - _ m( NaOH )
  2. B_ m( NaOH ) + _ m( NaCl ) - _ m ( NH ₄ Cl )
  3. C_ m ( NH ₄ OH ) + _ m ( NH ₄ Cl ) - _ m( HCl )
  4. D_ m ( NH ₄ Cl ) + _ m( NaOH ) - _ m( NaCl )

Correct answer

D. _ m ( NH ₄ Cl ) + _ m( NaOH ) - _ m( NaCl )

Step-by-step solution

According to Kohlrausch's law, limiting molar conductivity of NH ₄ OH _ m ( NH ₄ OH ) ^ = _ m ( NH ₄ Cl ) ^ + _ m( NaOH ) ^ - _ m( NaCl ) ^
