Acid-base indicators are compounds that change color when they become protonated or deprotonated. Because this color change occurs over a specific pH range, indicators can be used to approximate the equivalence point of an acid-base titration.

I'm not at this level of Chem but I'm using the Atoms, compounds, and ions course on the app, literally in 1 hour I have learned more about Chem than over 100 hours in school. I'm needing Chem for post secondary soon so this is a life saver

I promise it is simple I am not super great at chemistry but I perfectly understand this sh*t. It is a walk in the park for me... lol
Acid and Base indicators are used in titrations to see when the equivalence point is reached. pH pka the conc. Of conj base is greater than weak acid. If pH = Pka both conjugates are equal in concentrations. If we were to change pH in color between for example red and color so we choose an indicator as close as possible to pH color at equivalence point.
Thanks a ton, needing it
What program that he use to write and draw ?
Hi, could you please share your setup about your writing board? I am using epic pen right now but searching for better alternatives.
Please add a Propositional Logic Course

Poor indicator choice makes the titration pointless and useless Victor Krum. Might as well not even do the experiment as you are wasting your own time
