Color Changes of Eriochrome Black T
« on: November 04, 2012, 11:31:06 PM »
Why is Eriochrome Black T in HCl solution with added distilled water will remain red when there is no magnesium nitrate added?

and why is erichrome black T in NaOH solution with added distilled water will become red when there is no magnesium nitrate added? is it because of it is protonated ?

URGENT! please and thank you :D
