Addition of Silver Nitrate 1. Based upon the color, in which direction does the equilibrium shift?
Shifts Left.
2. Write an equation showing what happens when AgNO3 is added, and explain why the equilibrium shifts.
Addition of Water
3. Explain the equilibrium shift that occurs when water is added to the original equilibrium reaction.
Cu(H2O)62+(aq) + 4Cl–(aq) D CuCl42–(aq) + 6H2O(l)
blue green
Temperature Changes
4. Write "heat" on either the left or right side of this equation, based upon observations from the addition and removal of heat in steps 3 and 4, respectively, and the corresponding shifts in equilibrium.
+ Cu(H2O)62+(aq) + 4Cl–(aq) D CuCl42–(aq) + 6H2O(l) +
Blue Green

See explanation

Explanation:

When AgNO3 is added to the system the equilibrium position shifts towards the left hand side because of the formation of AgCl as a precipitate thereby sequestering the Cl^- from solution.

AgNO3(aq) + Cl^-(aq) > AgCl(s) + NO3^-(aq)

[Cu(H2O)6]^2+(aq) + 4Cl^–(aq) > [CuCl4]^2–(aq) + 6H2O(l)

The equilibrium of this reaction shifts towards the right as more Cl^– is added making the color of the solution to change from blue to green.

[Cu(H2O)6]^2+(aq) + 4Cl^–(aq) + heat > [CuCl4]^2–(aq) + 6H2O(l)

This reaction is endothermic. addition of heat makes the solution to turn green (equilibrium shifts towards the right) while removal of heat makes the solution to turn blue (equilibrium shifts towards the left).

indium, and thallium have three electrons i think
