Le Chatelier’s Principle and Chemical Equilibrium
Then you left the two flaks to stand for several minutes after the addition of NaOH, why did the contents of flask A again change colour back from blue to yellow?Explain your answer in terms of this equation (Hln(aq) + H2O (l) <> H3O+ (aq) + ln- (aq)

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? Consider equilibriums: Hin + H2O + H30+ + In [2 marks] CO2(g) +...
