2) An acid anhydride is
a)HCl
b)H2O
c)SO2
d)CaO

3) The compound formed when a metal replaces the hydrogen in an acid is a(n)
a)acid
b)base
c)salt
d)indicator

4) A metal which will form a base when reacted with water is
a)Zn
b)Na
c)Fe
d)Cu

5. Acid solutions cause reddish-purple phenolphthalein to become ______?

6. To produce a given acid, react sulfuric acid with the _____ of the acid desired.

7. An oxide which dissolves in water to form an acid or base is called a(n) ____.

8. A base is also known as a proton ____.

9. A base consists of a metallic element or radical combined with one or more ____ radical.

10. A base may be produced by reacting a salt of the desired base with _____.(Write out the compound name.)

11. A substance which shows the presence of an acid or base by changing color is called a(n) ______.

Answer 1

1. c) bases

2. c) SO2 anhydride of H2SO3 sulfurous acid

3. c) salt

4. b) Na sodium

5. colorless

6. salt

7. anhydride

8. acceptor

9. OH-

10. potassium hydroxide (slightly stronger base than NaOH)

11. indicator

Answer 2

1. Bases
2. SO2
3.Salt
4. Na (actually, Zn can also be made to react with water to give Zn(OH)2, although you haqve to work on it.)
5. Colorless (water-white)
6. Salt, anion
7. Basic anhydride
8. Acceptor (Bronsted-Lowry theory of acids and bases)
9. Hydroxide
10. This cannot be done. For example to make NaOH from the salt NaCl, one would have to electrolyze aqueous NaCl, but there is nothing one can "add" to NaCl to make it into NaOH.
11. Indicator

Answer 3

1.) Hydrocyanic acid 2.) Hydro- 3.) Phosphorous Acid 4.) Phosphoric Acid 5.) Sulfate ion SO42- 6.) HCLO3
