$\text{Statement II is incorrect........}$

#### Explanation:

Whereas $\text{statement I}$ seems to be kosher.

For $\text{statement I}$ you have set up an equilibrium between dissolved and undissolved salt. Given equilibrium conditions, the rate of dissolution is equal to the rate of precipitation:

$N a C l \left(s\right) r i g h t \le f t h a r p \infty n s N {a}^{+} \left(a q\right) + C {l}^{-} \left(a q\right)$

But $\text{statement II}$ is whack. The given equilibrium will occur WHATEVER the mass of undissolved salt. The amount of ions in solution is characteristic of a given temperature. Is it clear what I argue?
