Strong and Weak Acids/Bases

Name the following in order:
HCl, HBr, HI

• hydrochloric acid, hydrobromic acid, hydroiodic acid
• chloric acid, bromic acid, iodic acid
• chlorous acid, bromous acid, iodous acid
• hydrochlorous acid, hydrobromous acid, hydroiodous acid

Name the following in order:
H₂SO₄, HNO₃

• sulfurous acid, nitrous acid
• hydrosulfuric acid, hydronitric acid
• sulfuric acid, nitric acid
• hydrosulfurous acid, hydronitrous acid

Strong acids and bases...

• do not break apart into ions (non-electrolyte)
• partially break apart into ions (weak electrolyte)
• completely break apart into ions (non-electrolyte)
• completely break apart into ions (strong electrolyte)

What are the weak acids and bases?

• all acids and bases are weak
• if not classified as strong, the acid/base is considered weak
• all acids and bases are strong
• there are more strong acids and bases than there are weak acids/bases

Which of the following is NOT a strong acid

• Sulfuric acid

• Hydrochloric acid

• Perchloric acid

• Hydrofluoric acid

• a pH neutral substance
• the base would destroy the acid
