HSC Chemistry experiment: Natural pH indicator from Anthocyanin (Red Cabbage Juice)

[MaXxChiX]

What percent of ethanol is best for extracting anthocyanin from the cabbage: 70% or 100% ethanol? Does it even matter?

[MaXxChiX]

@MaXxChiX Nvm! I found the answer.

@MaXxChiX For best results use 1:99 ratio of HCl and ethanol, however methanol is more effective and has a lower boiling point therefore extraction requires less energy, purification is simpler by the use of methanol aswell.
