You are familiar with the fact that oxygen could dissolve in the water. But if somebody asks you to prove that oxygen can dissolve in water, how will you do that?
Let us do this experiment and see whether you could add more oxygen to the water
Step 1
Fill one plastic bottle (60%) with water from the same source from which you collected water for testing oxygen.
Step 2
Close the lid tightly and shake it well for 6 minutes vigorously
Step 3
Measure the amount of oxygen present in this water sample following Winkler’s method
Step 4
Now add the value of oxygen you got in the first and second experiments (before and after shaking the water) into a spreadsheet and make a graph and compare.
