How i prepare the bromocresol green indicator (blue to yellow) from its powder?

Answer 1

Bromocresol green acid-base indicator solution:

pH Range 3.8 to 5.4, Color change Yellow to Blue

Accurately weigh 0.1 g of bromocresol green into a brown container flask. Add 14.3 ml of 0.01 M NaOH + 235.7 ml distilled and deionized water and swirl to dissolve (Lide 1991).
