Question

Describe two techniques used to measure the PH of a solution

Answer 1

Answer:

ph paper, or a ph meter

Explanation:

Answer 2

Answer:

Measure H+ concentration or measure OH- concentration

Explanation:

Since pH is basically the number of H+ ions in a solution, that's what you're trying to find. (it's actually -log of H+, which is irrelevant since this is a conceptual question). You can do this with a variety of chemicals.

And p,OH is always 14-pH. So you can also use the number of OH- ions to find p,OH, which can find pH.

hope this helps
