Acids and Bases SL

Question 1

Distinguish between strong and weak acids properties

Answer 1

Strong acids have higher conductivity, weak acids have lower conductivity

Strong acids react faster, weak acids react slower

Strong acids are relatively dangerous, weak acids are relatively safe

Question 2

How is a conjugate acid made?

Answer 2

By adding a proton

Question 3

Outline Lewis theory

Answer 3

Lewis acids are electron pair acceptors, lewis bases are electron pair donors

Question 4

Difference between bases and alkalis?

Answer 4

Bases are soluble alkalis

Question 5

Difference between weak and strong acids

Answer 5

Strong acids dissociate completely into their ions in solution, weak acids dissociate only partially

Question 6

Relationship between ionic products of water (Kw) and conditions

Answer 6

Increases as temp increases, because the concentration of H ions and OH ions increases. pH also increases because a higher temp means faster dissociation, more H ions are produced, and therefore it is more acidic.
