buffers

Question 1

what is an acidic buffer

Answer 1

buffers with pH of less than 7

Question 2

how do acidic buffers resist an acid

Answer 2

most of the H+ Ions join with A- ions to form HA shifting equilibrium to the left reducing H+

Question 3

How do acidic buffers resist a base

Answer 3

most of the OH - react with H+ To form water
causes more of HA to dissociate into H+ to shift equilibrium right

Question 4

how is the pH of blood maintained by buffers

Answer 4

carbonic acid hydrogencarbonate buffer system

Question 5

what happens if blood is too acidic

Answer 5

HCO3 - ions from buffer system react with excess H+ and equilibrium shifts left

Question 6

what happens if blood pH is too high

Answer 6

H2CO3 ions dissociates and equilbrium shifts to right increasing H+ Conc
