˄0m(H2O) is equal to ______________.

(i) ˄0m(HCl) + ˄0m(NaOHl) – ˄0m(NaCl)

(ii) ˄0m(HNO3) + ˄0m(NaNO3) – ˄0m(NaOH)

(iii) ˄0m(HNO3) + ˄0m(NaOH) – ˄0m(NaNO3)

(iv) ˄0m(NH4OH) + ˄0m(HCl) – ˄0m(NH4Cl)

 

Correct Answers:

(i) ˄0m(HCl) + ˄0m(NaOHl) – ˄0m(NaCl)

(ii) ˄0m(HNO3) + ˄0m(NaNO3) – ˄0m(NaOH)

Explanation: According to the Kohlrausch law of independent migration of ions, ˄0m(H2O) is equal to ˄0m(HCl) + ˄0m(NaOHl) – ˄0m(NaCl) and ˄0m(HNO3) + ˄0m(NaNO3) – ˄0m(NaOH)
