Calculate the molar conductivity of CH ₂ ClCOOH at zero concentration if molar conductivities of HCl , KCl and CH ₂ ClCOOK at zero concentration are 4.2,1.4 and 1.1 ⁻¹ ~cm ^2 ~mol ⁻¹ respectively.
Options
- A3.9 ⁻¹ ~cm ^2 ~mol ⁻¹
- B4.5 ⁻¹ ~cm ^2 ~mol ⁻¹
- C6.6 ⁻¹ ~cm ^2 ~mol ⁻¹
- D1.7 ⁻¹ ~cm ^2 ~mol ⁻¹
Correct answer
A. 3.9 ⁻¹ ~cm ^2 ~mol ⁻¹
Step-by-step solution
aligned _ CH ₂ ClCOOH ^ & = _ CH ₂ ClCOOK ^ + _ HCl ^ - _ KCl ^ _ CH ₂ ClCOOH ^ & =1.1+4.2-1.4 & =3.9 ⁻¹ ~cm ^2 ~mol ⁻¹ aligned
