# How does a solvent affect the solubility of an ionic compound?

Jul 17, 2018

Water is a polar, protic solvent that is capable of solvating both positive ions and negative ions. When we dissolve a salt, say common salt in water, we write...$N a C l \left(a q\right)$...we really mean something of the order of ${\left[N a {\left(O {H}_{2}\right)}_{6}\right]}^{+}$ and ${\left[C l {\left({H}_{2} O\right)}_{4 - 6}\right]}^{-}$...this is what mean when we speak of aquated ions. A couple of solvents capable of solvating ionic solutes are $H F$, and $N {H}_{3}$, and both of these are protic polar solvents (tho they are certainly not as convenient as water to use!).
