Salts should generally be soluble in nonpolar organic solvents.
a. true
b. false

b. False

Explanation:

Salts are generally soluble in polar aqueous solvents. Salts are insoluble in nonpolar organic solvents. For example, NaCl is salt soluble in water (polar aqueous solvent) but not in benzene (nonpolar organic solvent).  

NaCl dissolves in water to form Na⁺ and Cl⁻ ions. Each of the ions gets surrounded by water molecules thus becoming solvated and stable.  

NaCl + H₂O → Na⁺ + Cl⁻

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
