8. Наибольшее число анионов образуется в растворе при диссоциации 1 моль

Upon dissociation of 1 mole of sulfuric acid (H2SO4), it yields 2 moles of H+ ions and 1 mole of SO4^2- ions. Upon dissociation of 1 mole of potassium sulfate (K2SO4), it yields 2 moles of K+ ions and 1 mole of SO4^2- ions. Upon dissociation of 1 mole of magnesium sulfate (MgSO4), it yields 1 mole of Mg^2+ ions and 1 mole of SO4^2- ions. Upon dissociation of 1 mole of aluminum sulfate (Al2(SO4)3), it yields 2 moles of Al^3+ ions and 3 moles of SO4^2- ions. Therefore, aluminum sulfate produces the largest number of anions (sulfate ions).
