Acids, Bases and pH

Question 1

What is a bronsted-lowery acid?

Answer 1

A proton donor - something that gives up H+

Question 2

What is a bronsted-lowery base?

Answer 2

Proton aceptor - something that accepts H+

Question 3

What does the dissociation of acids and bases in water depend on?

Answer 3

The amount of dissociation depends on how strong the acid or base is. stronger acids and bases dissociate the most/ almost completely

Question 4

What has to be present in order for an acid to dissociate?

Answer 4

A base that is ready to accept the dissociated H+ ions

Question 5

What does water dissociate into

Answer 5

hydroxodium ions and hydroxide ions

H20 + H20 –> H30+ + OH-

Question 6

where does the equilibrium lie for H20 + H20 –> H30+ + OH- and why?

Answer 6

Water only dissociates a tiny amount so the equilibrium lies more to the left where there is the H20

Question 7

what is the kc value of water under standard conditions known as

Answer 7

Kw
