just struggling to understand why its 8. b)
similar principle to 2012 hsc question here http://community.boredofstudies.org/240/acidic-environment/305880/degree-ionisation.html
shouldnt H+ decrease and therefore HA becomes more ionised by shifting right? HA <--> H+ + A-
HEEELLPPP MEEEE
You are misunderstanding cause and effect. Q8: Graph gives you that as temperature decreases, pH increases (this is the effect). Now you have to find the cause - so 8 is B (it must have become less ionised and H+ concentration decrease)
