उत्तर

\[\ce{\Lambda^0_m(NH4OH)}\] is equal to \[\ce{\mathbf{\underline{\Lambda^0_m(NH4Cl) + \Lambda^0_m(NaOH) - \Lambda^0_m(NaCl)}}}\]

Explanation:

(i) \[\ce{NH4Cl <=> NH^{+}4 + Cl-}\]  

(ii) \[\ce{NaCl <=> Na+ + Cl-}\]  

(iii) \[\ce{NaOH <=> Na+ + OH-}\]   

(iv) \[\ce{NH4OH <=> NH^{+}4 + OH-}\] 

To get equation (iv),

\[\ce{\Lambda^0_m(NH4Cl) + \Lambda^0_m(NaOH) - \Lambda^0(NaCl) = \Lambda^0_m(NH_4OH)}\]
