The limiting molar conductivities ( ₀ ) for NaCl , KBr and KCl are 126, 152 and 150 ~S ~cm ~cm ^2 ~mol ⁻¹ respectively. What is the A₀ of NaBr ?
Options
- A128 ~S ~cm ^2 ~mol ⁻¹
- B302 ~S ~cm ^2 ~mol ⁻¹
- C278 ~S ~cm ^2 ~mol ⁻¹
- D176 ~S ~cm ^2 ~mol ⁻¹
Correct answer
A. 128 ~S ~cm ^2 ~mol ⁻¹
Step-by-step solution
aligned _ 0( NaBr ) & = _ 0( NaCl ) + _ 0( KBr ) - _ 0( KCl ) & =126+152-150 & =128 ~S ~cm ^2 ~mol ⁻¹ aligned
