Answer 1

Answer:

Oe can use paper treated with litmus solution (litmus paper) or universal indicator paper strips.

Explanation:

The reason for the choice is :-

1.Litmus paper and universal indicator paper strips are easily available.

2.they give instant and precise result

Answer 2

Answer:

The easiest way to approximate ph level is the ph paper because there are no experimentation required and it is very handy. so it is the best way to approximate the ph level of a lake, especially when you are outdoors, and it is just an initial reading of the ph. so ph paper will do.

Explanation: Not a sample response.
