![### Lab 2: Cobalt Chloride Equilibrium Experiment
In this experiment, we will observe and analyze the equilibrium of the reaction:
\[ \text{CoCl}_4^{2-} + 6 \text{H}_2\text{O} \rightleftharpoons \text{Co}(\text{H}_2\text{O})_6^{2+} + 4 \text{Cl}^- \]
**Instructions:**

**Objective:**
Explain your observations for each of the following scenarios:
1. **On Addition of 1 M HCl**
2. **On Addition of H\(_2\)O**
3. **On Addition of Co(H\(_2\)O\(_6\))\(^{2+}\)**
**Questions:**
- **(A)** Where will the equilibrium shift upon the addition of a particular reagent? (Write the complete equation to explain).
- **(B)** What color change was observed? Explain why.
**Key Considerations:**
- The first test tube serves as the control.
4. **Thermal Effects:**
- Why does the equilibrium shift blue when the test tube is placed in warm water? Provide an explanation.
5. **Cold Water Bath:**
- What is the effect on the equilibrium mixture in a cold water bath? Explain your observations.
