Watch the following video that illustrates a series of experiments that demonstrate Le Chateliers principle: https://www.youtube.com/watch?v=ZOYyCTvLa9E
In this video, you will observe several examples of external stresses that act upon the equilibrium chemical reaction:
Fe_aq^(+3)+SCN_aq^(-1)Fe(SCN)_aq^(+2)
Each stress will serve to either add or remove reactant or product.
- Describe what happens when iron nitrate or potassium thiocyanate (reactant) are added to the control tube? Describe your observation in the context of Le Chateliers principle.
- Describe what happened when sodium hydroxide was added to the control tube? Does the addition of sodium hydroxide add or remove a reactant or product? If so, clearly state the effect of adding sodium hydroxide and how equilibrium shifts to relieve this stress.
- Similarly, describe what happened when potassium chloride was added to the control tube? | PLACE YOUR ORDER NOW AT brainshareweb.com |
- Next, describe what happened when silver nitrate was added to the control tube?
- Lastly, describe what happens when Mercury (II) Nitrate was added to the control tube?
