What are the Bronsted-Lowry definitions of acid and base? 
Acids donate H+ and Bases accept H+ (BAAD) 
 
 
 
What is the difference between a strong acid and a weak acid? Give examples of each. 
Strong acids completely dissociate into anion and H+. Weak acids do not dissociate completely into anion and H+, they form an equilibrium system and reform acid and anion and H+ continuously. 
 
Strong acid ex. HCl and H2SO4 
Weak acid ex. H3PO4 and HC2H3O2 
 
 
 
What is the difference between a strong ...
