1. Add the appropriate amount of Solution A (see table below for volumes) and amount of water to the 100ml beaker.

1. Add 5mL of Solution A and 5ml of water into a 100mL beaker (Label A/water).

Removed: 12d11

2. Pour out the appropriate amount of Solution B into 25ml graduated cylinder.DO NOT ADD TO 100ml BEAKER UNTIL HAVE STOPWATCH

Changed: 14c13

3. Add all Solution B into 100ml beaker at once, start stopwatch and swirl solutions until "solution turns blue".

2. Add 10mL of Solution B into another 100mL beaker (Label B).

Removed: 16d14

4. Record time.

Changed: 18c16,31

5. Dispose of solution into sink and clean 100ml beaker. Use only one graduate cylinder for each solution for all trials

3. Place both 100mL beakers into the "cold water" bath and let solution get to temperature for 3-5mins.

4. Once at temperature, pour Solution A/water into reaction beaker (another 100mL beaker) and then Solution B.

5. Start recording time when Solution B is added to reaction beaker (i.e. Solution A/water).

6. When you "see change", record the time it took to get there, as Lower (cold) temp:.

7. Repeat the same procedures (1-6) but just with the hot water bath. Record as Higher (Warmer) Temp.
