16. a. all but the second. Acids bases and salts are electrolytes b. CH3COOH, acetic acid
c. large amounts of hydrogen ions d. Ba(OH)2, it's a base e. Ba(OH)2, it produces the most ions in solution
17. 35.2 - 23.2 = 12.0 mL
18. phenolpthalein, it changes color near the neutralization point
19. MaVa = MbVb trial 1 1.2(10.0) = 12.2X trial 2 1.2(10.0) = 11.0X trial 3 1.2(10.0) = 12.0X
trial 4 1.2(10.0) = 12.5X add up molarities and divide by 4 comes to 0.98 ish
20. Using multiple trials reduces error
21. colorless to pink
22. 0.30(42.2) = 60.0X
23. two 0.30 has two sig figs
24. hydrogen ions, hydronium ions
25. 5, it moves 3 ph levels down
26. yellow
27. 1.4(15.40) = 22.10X
28. (0.95 - 0.83)/0.83 all times 100
29. 7, up two places
30. barium hydroxide
