Worksheet - Acids, Bases and Salts
1. I am pure water. When heated my pH (increases, decreases), because more of my water molecules dissociate.
2. I am a 0.020 M solution of weak acid, HA. If I only dissociate to the extent of 1.50%, what is the value of my Ka?
3. I am a 0.20 M solution of hydrocyanic acid, HCN, with a Ka of 4.93 x 10¯ 10 . What is my pH?
4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 , what is my pH?
5. I am a substance who turns blue litmus red, neutralizes bases, and tastes sour. What am I?
6. I am a species who turns red litmus blue, neutralizes acids, and tastes bitter. What am I?
7. I am a 0.020 M solution of a weak acid, HA, who dissociates to the extent of 3.5%. What is the value of my Ka?
8. I am a Bronsted-Lowry acid. Therefore, I am a _________________donor.
9. I am a Bronsted-Lowry base. As a result, I am a proton ______________.
10. I am a bicarbonate ion, HCO3¯. Because I can both donate and accept a proton under certain conditions, I am called a(n) ______________________ species.
True and False
11. Water is neither an acid nor a base in the Arrhenius system.
12. The [H+] in pure water is normally 1.00 x 10-7.
13. The reaction of an acid with a base to produce a salt and water is an endothermic reaction.
14. The larger the value of Ka, the stronger the acid.
15. The stronger an acid, the stronger its conjugate base.
16. The [H+] in pure water is normally 1.00 x 10-14.
17. The strongest base that can exist in aqueous solutions is the OH¯ ion.
18. A solution with a pH of 13 would be acidic.
19. A solution with a pOH of 12 would be basic.
20. The hydrogen ion concentration in a solution with a pH of 5.65 is ten times that of one with a pH of 6.65.
