Chemistry Questions - Solubility?

Question

Why is water an excellent solvent for most ionic compounds, and polar-covalent molecules, but not for non-polar molecules?

What are two factors that affect the solubility of an ionic compound in water?

And why is a non-polar solute does not dissolve in a polar solvent?

Thanks in advance!

Answer 1

These are standard text book questions. You need to read the chapter and understand the chapter and then you will understand.

Water is polar; it solvates by aligning its the free nonbonding electrons of oxygen with the + charged ions and engages in H bondign with the - charged ones.

Polar covalent compounds align with the water polarity.

Nonpolar compounds do not align well (if at all) so there is a miscibility gap.

If you understand the above answers, you can answer the rest. If you do not understand the above, review your text. You won't pass the final exam unless you understand this.

Answer 2

Hmm...it looks like you have a lot of punctuation.
