14-16. 	Refer to Section 4-2. 
Three major classes of compounds are electrolytes: 
		Strong Electrolytes 	Weak Electrolytes 
	(1) acids 	HCl, HCI04 	CH3C00H, HF 
	(2) soluble bases 	Na0H, Ba(0H)2 	NH3, (CH3)3N 
	(3) soluble salts 	NaCl, KN03 	Pb(CH3C00)2 
This is one of the very few soluble salts that is a weak electrolyte. 
Therefore, the three classes of compounds which are strong electrolytes are strong acids, strong soluble bases and 
soluble salts. 
	14-18. 	Refer to Sections 4-2 and 4-11. 	I 
A salt is a compound that contains a cation other than H+ and an anion other than the hydroxide ion, 0H-, or the oxide 
ion, 02-. A salt is a product of the reaction between a particular acid and base and consists of the cation of the base 
and the anion of the acid. For example, 
Na0H + HCl ---> NaCl + H20 
	base 	acid 	salt 
14-20. 	Refer to Section 4-2. 			I 
(a) HCl(aq) ---> H+(aq) + Cl-(aq) 
(b) HN03(aq) ---> H+(aq) + N03-(aq) 
(c) HC104(aq) ---> H+(aq) + C104-(aq) 
14-22. 	Refer to Section 4-2 and Table 4-7. 	I 
Common strong bases include: 
	lithium hydroxide 	Li0H 	calcium hydroxide 	Ca(0H)2 
	sodium hydroxide 	Na0H 	strontium hydroxide 	Sr(0H)2 
	potassium hydroxide 	K0H 	barium hydroxide 	Ba(0H)2 
	rubidium hydroxide 	Rb0H 
	cesium hydroxide 	Cs0H

Household ammonia is the most common weak base. 
It ionizes as follows: 
NH3(aq) + H20(l) ~ NH4+(aq) + 0H-(aq)
