Question

I'm not so good at writing chemical reactions so a little help would be appreciated:

Write the following chemical reaction for the following:

a) Blue to Yellow color change

b) Yellow to blue color change

HERE is the table of chemical reactions during my experiment:

CONTENTS Color

Bromophenol Blue+(1)HC1 Yellow

Bromophenol Blue(control) Blue

Bromophenol Blue+(1)NaOH Blue

Bromophenol Bue+(1)HC1+(2)NaOH Blue

Bromophenol Blue+(1)NaOH+(2)HC1 Yellow

Bromophenol Blue+(1)HC1+(2)NaOH+(3)HC1 Yellow

Bromophenol Blue+(1)NaOH+(2)HC1+(3)NaOH Blue

THANK YOU.

bromophenol is a indicator its colour in acidic solution is yellow & blue in basic solution.

Bromophenol + HCl ---- acidic solution------yellow colour

Bromophenol +NaOH- basic solution--------blue colour

bromophenol +2NaOH +HCl ----basic solution--blue colour([OH-]>[H+])

bromophenol+NaOH +2HCl---acidicsolution---yellow colour ([H+]>[OH-])

Ind + HCl +2NaOH +3HCl ---acidic solution----yellow colour([H+]>[OH-])

Ind +NaOH +2HCl+3NaOH---basic solution-----blue colour ([OH-]>[H+])

NaOH=Base, HCl= acid
