need help with these questions.
Part I.A 1. Why did the indicator initially turn blue when NaOH was added to flask A? Consider equilibrium: Hin + H2O + H2O + In [1 mark] 2. When you left the flask A to stand for several minutes after the addition of NaOH, why did the contents of the flask A slowly change colour back from blue to yellow?
