Chemistry: Manners of Dissolving Substances 1. The problem statement, all variables and given/known data "Dissolving a substance can be achieved through dissociation, ionization, or dispersion. Which manner of dissolving occurs to each of the following substances? Substances are: acetic acid, methanol and copper (II) sulfate." 2. Relevant equations Acetic Acid: CH3COOH, Methanol: CH3OH, Copper (II) sulfate: CuSO4 3. The attempt at a solution Acetic acid: Dissociation. Methanol: Dispersion. Copper (II) sulfate: Dissociation. I am confused as to why some sources suggest that acetic acid would dissolve through ionization. Isn't acetic acid ionic? If not, how would I go about discerning when a substance is ionic or not, particularly when the compound contains one or more polyatomic ions? Please take into account that I am only at a intermediate high school level of education. I will not be able to understand any explanation that requires me to have attended a grade twelve or university level of chemistry. I greatly appreciate any help that can be provided. Thank you, Eric.
