Limiting molar conductivity of $NH_4OH$
$[i.e.\, \Lambda ^o_{m(NH_4OH)}]$ is equal to
- A$\Lambda ^o_{m(NH_4Cl)} + \Lambda ^o_{m(NaCl)} - \Lambda ^o_{m(NaOH)}$
- B$\Lambda ^o_{m(NaOH)} + \Lambda ^o_{m(NaCl)} - \Lambda ^o_{m(NH_4Cl)}$
- C$\Lambda ^o_{m(NH_4OH)} + \Lambda ^o_{m(NH_4Cl)} - \Lambda ^o_{m(HCl)}$
- ✓$\Lambda ^o_{m(NH_4Cl)} + \Lambda ^o_{m(NaOH)} - \Lambda ^o_{m(NaCl)} $
