Thanks for leaving a comment and asking this question. I think you are right too. I will try to answer, but I am just someone who has studied certain concepts and I am not an expert. From what I know, it is precisely thanks to the polar nature of water that many salts can dissolve in it. Water is in fact a polar solvent. Water molecules have an asymmetric distribution of charges. Oxygen is slightly negative, hydrogens are slightly positive. This makes them capable of interacting with the ions present in salts.
