Making indicator stop
Earlier today I was at a local store and lost my head in the heat of the
moment! I ended up getting a gallon of glacial acetic acid and then went online
and ordered 10 grams of bromocresol purple dye to make an indicator stop.
Has anyone here made their own indicator stop and if so how much of the bromostresol purple
do I need to add to a gallon of 28% stock?
