1a)  The amount that it iodizes in aqueous solution.
b)  Strong acid = Hydrochloric acid,  Nitric acid
Weak acid =  Sulfuric acid, hydrosulfuric acid

2.  Monoprotic acid;  is an acid that can donate one proton (hydrogen ion) per molecule.  
Diprotic acid;  is an acid that can donate two protons per molecule.
Triprotic acid is an acid able to donate three protons per molecule.  
Mono = hydrochloric acid  
Di = sulfuric acid
Tri = phosphoric acid

3a)  Organic acid; is an organic compound that contains an acid group, the carboxyl group.
Mineral acid; acid made from minerals.

b)  Organic;  acetic acid
Mineral;  sulfuric acid, nitric acid, hydrochloric acid

5f) hydrofluoric acid
g)  nitrous acid
h) Perchlroric acid
i) Phosphoric acid
j) Hypochlorous acid
k) Carbonic acid

6f) H 3 PO 4
g) HClO 2
h) HNO 2
i) H 2 SO 4
j) H ? PO ? 

8.  Because H 3 PO 4  is a weak electrolyte, and HCL is a strong electrolyte.

9.  ???

10a)  Concentration of OH-
b) Strong = hydride ion, moderate = sulfate ion,  weak = perchlorate ion.
