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

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
