Question

4.   Predict whether the reaction shifts right or left when 12 M HCl is added. Explain your prediction. [Note: Use the balanced equation, Co(H₂O)₆²⁺ + 4Cl^- CoCl₄^2- + 6 H₂O, to explain the shift. Specifically, which component of the equation is added? And identify the result according to Le Chatelier's Principle.]

5.   Identify the mL of HCl needed to shift the equilibrium.

6.   Calculate the value of the equilibrium expression at the new concentrations. (Show your work.)

PART C

7.   Predict whether the reaction will shift left or right when AgNO₃ is added. Explain your prediction.

8.   Identify the number of mL of AgNO₃ needed to just begin to form a visible precipitate?

Answer 1

5,.6,7,8 can't eb answered without given concentration of other reactants and products

I can answer 4 for you:

4)
Co(H2O)62+ + 4Cl- ------->   CoCl42- + 6 H2O

HCl forms H+ and Cl- as
HCl     ----->   H+   +   Cl-

When Cl is added, we are adding more of Cl- and since Cl- is reactant, According to Le Chatelier's Principle equilibrium will shift in taht direction where Cl- is being consumed.

So, equilibrium will shift towards right
