Question
- Why was it necessary to keep the total volume of the reagents after mixing constant in all the kinetic runs (i.e., why was it necessary to add distilled water in inverse proportion to the quantity of Solution 1 that was required)?
Transcribed Image Text:**Part B – Reactions Varying Concentrations**
**Procedure Overview:**
Conduct two trials for each variation.
**TUBE 1 Preparation:**
- **Run A:**
- Mix 1.0 mL Solution 1 with 4.0 mL distilled water.
- **Run B:**
- Mix 2.0 mL Solution 1 with 3.0 mL distilled water.
- **Run C:**
- Mix 3.0 mL Solution 1 with 2.0 mL distilled water.
- **Run D:**
- Mix 4.0 mL Solution 1 with 1.0 mL distilled water.
- **Run E:**
- Use 5.0 mL Solution 1 with 0.0 mL distilled water (undiluted).
**TUBE 2 Preparation:**
- For each of Run A to E, add:
- 1.0 mL Solution 2
- 4 drops of starch
**Instructions:**
1. Combine Solution 1 and distilled water as directed.
2. Prepare Solution 2 by adding 4 drops of starch and stir thoroughly.
3. Before proceeding, add the mixture from TUBE 1 to TUBE 2.
