study the PH and presence of any living organisms of the given material
different water sample
Answers
Answer:
by ph paper and ph meter
Explanation:
Take two clean and dried test tubes.
Add the collected two different water samples into the two test tubes.
For a safer side, label the test tubes as A and B.
Dip the individual pH paper strips into the two different water samples.
Keep the strips on the tile and wait for the strips to dry.
Alternatively, pH levels of the water sample can also be found using the universal indicator solution.
Now, with the help of a dropper, add five drops of universal Indicator solution into both the test tubes.
Observe the change in colour in both the test tubes and compare the same with the colour chart.
To study the presence of living organisms
Take a clean dried test tube.
Add the collected water sample, preferably from a pond, into the test tube.
Leave the sample undisturbed, until the sediment settles at the bottom of the test tube.
Transfer a drop from the test tube on to a glass slide.
Gently place a coverslip on the slide using a needle.
Observe the entire slide under a compound microscope.
