I remember it being “d-d-d-drop the base” and while you swirled it would get pink but that would disappear, but as it got close, the pink would take longer to disappear, and when you got really close you could even do half drops to try and get the solution to be just the tiniest hint of pale pink. Then you were as close as possible to equalization without overshooting.
Looks like she already went far past the point of equalization? (Unless it’s been too long for me and I don’t remember chemistry).
Depends on the indicator.
BROMOTHYMOL BLUE BAYBAYYYYYYY
Red is acidic, she is dr
oiping the base to reduce the acidity.Maybe the usual way is to drip acid into the base (I don’t remember either), in which case a red indicator means she past the point of equalization.
