Salts consist of an anion and a cation component.d. Salts may be inorganic.e. Salts are usually acids.f. Salts are usually hydrophilic.
Open QuestionFill in the blanks:Acids donate _______________________ to an aqueous solution, which will lead to a(n) _______________________ in pH. In contrast, bases donate _______________________ to an aqueous solution and will _______________________ the pH. The pH of a solution with more OH−than H+ will have a(n) _______________________ pH.
