Record your observations in Table A. 5 Add 1 drop of 1.0 M AgNO3 to Well 4. Record your observations in Table A. 6 Add 1 drop of 1.0 M NaNO3 to Well 5. Record your observations in Table A. 7 After answering the questions below, rinse the contents of wells 1 - 5 into your waste beaker with a minimum amount of deionized water. Part B: CoCl42- + 6 H2O Co(H2O)62+ + 4 Cl- Equilibrium 1 In each of two wells of a ceramic spot plate, place 1 drop of 0.10 M Co(NO3)2. 2 Under the HOOD, add 12 M HCl (CAUTION) dropwise to Well 1, with gentle mixing (use a stirring rod) until a distinct color change occurs. Record your observations in Table B as "Well 1A". Now add deionized water dropwise to the same well until another color change occurs. Record this observation in Table B as "Well 1B". 3 Under the HOOD, add 12 M HCl (CAUTION) dropwise to Well 2, with gentle mixing (use a stirring rod) until a distinct color chan...
