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)
