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 ...
