Order of Reaction s
The order that you perform steps in a chemical reaction can greatly affect the outcome of an experi ment.
We are going to investigate this effect in the followi ng experiment.
o
o
o
3 beakers with samples of blue, yellow and red colou red water
6 test tubes (large enough to hold 25 ml of water)
One 50 ml measu ri ng cyl inder
One 0 ml measuring cylinder
One marker
ll
. Measure 7 ml of RED water from the beaker and pour into test tube A
Measure 21 ml of YELLOW water from the beaker and pour into test tube C
Measure 22 m of BLUE water from the beaker and pour into test tube E
Measure 5 ml of water from test tube A and pour into test tube B
Measure 6 m of water from test tube C and pour into test tube D
Measure 8 ml of water from test tube and pour nto test tube
Measure 5 ml of water from test tube C and pour into test tube B
Measure 4 ml of water from test tube E and pour into test tube D
Measure 6 ml of water from test tube A and pour into test tube F
0. Measure how much water is n each test tube usi ng the measu ri ng cyl inder
Results:
Draw a table indicating each test tube and its colour after you have performed this experi ment

Discussion:
I. What happened if you correctly followed the steps in order?
………………………………………………………………………………………………………………
2. What would have happened if you skipped a step or performed them incorrectly?
……………………………………………………………………………………………………………..
3. Why is it important to follow a method exactly as it is written in science?
……………………………………………………………………………………………………………..
4. Thin k about more complex reactions involving m ultiple steps and multiple chemicals
List TWO thi ngs that coul d go wrong if you don't follow the steps properly
