Equilibrium and Le Chatelier Principle
According to Le Chatelier's principle: What is going to happen to the color if you add more CuCl42- and why? The Kc is the equilibrium constant, the large the number the more product is favored. System 1: Cu²+(aq) + 4C1 (aq) = CuC142-(aq) Blue/Green Green/Yellow Kc or lc [CuCl2-] [Cu2+][C1-]4 O It will turn more Blue/Green and since you are adding extra chlorine ion O It will turn more Green/Yellow and since you are adding...

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) +...
what us question 7 and 8 ? i do not understand it.

Need help for
answering first part(1) color change is due to presence? And what
was the reason for the equilibrium turn to reverse direction? And
also last 2 questions.!
