Question: BTB is a dye that indicates pH change. a) What color is BTB at acidic pH and at alkaline pH? b) What is the purpose

BTB is a dye that indicates pH change.

a) What color is BTB at acidic pH and at alkaline pH?

b) What is the purpose of adding BTB to reaction Flasks B-E?

  • Flasks B-E involves a substitution reaction of water, NaOH, C3H8O, indicator dye, and R-X in an organic solvent.

c) flask A contains water, NaOH, organic solvent C3H8O, indicator dye, and HCl (aq), without any R-X. What does this flask reveal?

d) Is BTB an aromatic compound?

e) What are the main chemical differences between BTB in its acidic form versus its basic form?

please answer all questions. Thank you.
