Which one of the following,when 1 mole is dissolved in water,produces the solution with the lowest pH? A) KCl B) LiOH C) CaCl₂ D) AlCl₃ E) H₂SO₄

Question

Quizplus · Accepted Answer

When a strong acid is dissolved in water, it completely dissociates to form H+ ions, leading to a low pH. Among these options, only H₂SO₄ forms a strong acid (H2SO4) when it dissolves in water. The others either form neutral solutions (KCl, CaCl2) or basic solutions (LiOH, AlCl3). Therefore, option E, H₂SO₄, is the correct choice as it produces the solution with the lowest pH.
