D Question 3 1.5 pts Which of the following statements is INCORRECT? Strong electrolytes are much more soluble in water than weak electrolytes. All ionic compounds that are soluble in water are considered strong electrolytes. Nonelectrolytes are soluble molecular compounds. The extent to which an electrolyte dissolves in solution does not indicate whether it is strong or weak. o None of the above statements is incorrect.
