Question

Study the ph and presence of living organisms of the difference water sample

Answer 1

To study pH levels:

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.

Observation

Note the change in colour and associate the same with a broad range indicator paper to get a rough idea of the pH level.
