Could someone please explain Indicators...
For example, if you titrate NaOH with HCl (add HCl to uuknown concentration of NaOH)... what is the pka of a good indicator (qualitatively)? How do you determine this exactly?
AND
What is the indicator like when titrating HCl with a base?
Do you want the indicator to have a slightly lower pkb than HCl? Why?
Explain....
Thank you
