Non-polar Solute and Solvent. For the solute to dissolve, the dispersion forces between the molecules in the solute and solvent need to break. This only requires very little energy. However when the solute dissolves into the solvent, they are able to be make dispersion forces with each other. The making of these forces releases very little energy.Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry.

It does not occur in your molecules. According to me, while comparing acidic strength, we should remove H X + from both the compounds, hence we get C F X 3 − O X − and C C l X ...Now, coming to indium oxide, the formula of this compound as stated here is InX2OX3 I n X 2 O X 3, which bears a resemblance to the formula of AlX2OX3 A l X 2 O X 3 and GaX2OX3 G a X 2 O X 3 which we stated above. So, I would expect this oxide to atleast have some amphoteric properties.Chemistry Meta Stack Exchange is moderated by you.
