Review Chapter 19 1.According to Arrhenius, what are the characteristics of acids and bases? ans: acids produce H + and based produce OH - 2.What type of solution has [OH-] > [H+] ? ans: basic or alkaline solution. 3. What type of acid is represented as HX ? ans: monprotic

4. According to Bronsted-Lowey each acid must have its _________________? ans: conjugate base. 5. Label the acid and base and their conjugates CO H 2 O  HCO OH - Ans: baseacid conjugate conjugate acid base 6. ______________ can act as an acid or a base, like water ans: amphorteric

7.According to Lewis definitions of an acid of base, Ca 2+ would be a ___________? ans: Lewis acid, can accept e - pairs 8.An acid of H 2 BX is what type of acid? ans: diprotic 9.What concept is represented by: (1 x ) (1 x ) = 1 x ans: Kw, auto ionization of water 10. Given a M solution of HCl, what is the pH? ans: 3.0

11. A solution contains 1 mole of HCl in 12 L of water. What is the pH/ ans: pH = A solution contains 5 g of HCL in 120 ml. What is the pH? ans: pH = How would you make 2.3 L HX with a pH 1.57? The molar mass of HX is 36 g/mole ans: 2.23 g HX into 2.3 L water

14.What is the [OH-] of a solution with a pH 5.6? ans: 3.98 x Given a pH = 2.3, what is the pOH? ans: What is the [OH-] in #15 above? ans: 2 x How does this agree with the pOH? ans: pOH = 11.7 therefore exp =
