(a)[1.0]
A $0\cdot01\text{ M}$ solution of $\text{NaCl}$ is diluted by adding water. What will happen to its specific conductivity and molar conductivity?
(b)[1.0]
Is it safe to stir $1\text{M AgNO}_3$ solution with a copper spoon? Explain.
(Given: $E^\circ(\text{Cu}^{2+}/\text{Cu}) = +0\cdot34\text{ V}$, $E^\circ(\text{Ag}^+/\text{Ag}) = +0\cdot80\text{ V}$)
(c)[1.0]
Two metals A and B have standard reduction potential values $-2\cdot37\text{ V}$ and $+0\cdot80\text{ V}$ respectively. Which of these will liberate $\text{H}_2$ gas from dil. $\text{HCl}$?
