Chapter 8, Problem 8.81E

(a) The salt ${\text{NaNO}}_3$ can be thought of as $\text{NaCl}+{\text{KNO}}_{\text{3}}-\text{KCl}$. Demonstrate that ${\Lambda }_0$ values show this type of additivity by calculating ${\Lambda }_0$ for ${\text{NaNO}}_3$ from ${\Lambda }_0$ values of $\text{NaCl,}{\text{KNO}}_{\text{3}}\text{and}\text{KCl}$ found Table 8.4. Compare your calculated value with the ${\Lambda }_0$ value for ${\text{NaNO}}_3$ in the table. (b) Predict approximate ${\Lambda }_0$ values for ${\text{NH}}_4{\text{NO}}_3$ and ${\text{CaBr}}_{\text{2}}$ using the values given in Table 8.4.
