1. what happens to the solubility of an ionic compound as the ionic strength of the solution increases (up to ≈0.5 m≈0.5 m )?
a. solubility increases
b. solubility decreases
2. why is there a correlation between the solubility of an ionic compound and the ionic strength of the solution?
a. the increase in the ionic strength increases the ionic atmosphere around an individual ion, increasing the contact between ions, and increasing the tendency for ions to bind together.
b. the increase in the ionic strength increases the concentration of aqueous ion pairs.
c. the increase in the ionic strength decreases the concentration of aqueous ion pairs.
d. the increase in the ionic strength increases the ionic atmosphere around an individual ion, shielding it from other ions, and decreasing the tendency for ions to bind together.
