of unknown concentration and titration is complete. What is the
approximate concentration of the HCl solution?
(A) 0.015 M
(B) 0.03 M
(C) 1.5 M
(D) 2.5 M
(E) 3.0 M- Which is true regarding an aqueous solution of H 3 PO 4 at 25°C ?
(A) It has a very large acid ionization constant.
(B) It has a bitter taste.
(C) The concentration of [OH−] > 1.0 × 10−7 M.
(D) It is a weak electrolyte.
(E) It can be formed by the reaction of a metal oxide and
water.
