Indicators Flashcards
1
Q
What happens at the colour transition?
A
Ka=H+
2
Q
How can you pick the right indicator for a reaction?
A
You can base it off either the pH or the pKa of the solution.
3
Q
When does the equivalence point occur?
A
when H+=OH-
4
Q
What is the end point of the reaction?
A
When the pH range for the indicator causes colour change and so you can also match the indicator to the equivalence point
5
Q
What occurs at the half equivalence point?
A
pH=pKa
6
Q
why is there no buffer region in a strong acid base reaction?
A
The solution dissociates fully
