*(REDO LATER)* Lecture 22

Question 1

What are the 7 strong acids?

Answer 1

• HNO3 (nitric acid)
• H2SO4 (sulfuric acid)
• HClO4 (perchloric acid)
• HClO3 (chloric acid)
• HCl (hydrochloric acid)
• HBr (hydrobromic acid)
• HI (Hydroiodic acid)

Question 2

Concept: what does molarity say about the strength of an acid or base?

Answer 2

• NOTHING; the strength of an acid depends on the extent of ionization and NOT the concentration

Question 3

differentiate between strong, weak, and non electrolytes

Answer 3

• strong: soluble salts, strong acids and bases, will light a bulb
• weak: weak acids and bases
• non electrolytes: molecular compounds

Question 4

If an acid reacts with carbonates/bicarbonates it produces…

Answer 4

• a salt, CO2, and water

Question 5

if an acid reacts with metals it porduces

Answer 5

• single replacement reaction, releases H2 gas and forms a salt
• check solubility/activity table tho

Question 6

Acid base titration

• define
• define indicator/ purpose/ color change signifies what

Answer 6

• controlled reaction of unknown concentration of acid with known concentration of base (or unknown base with known acid)
• substance that changes color in response to a chemical change; signifies end point of reaction has been reached
