how can you determine ph of a solution

Question

Accepted Answer

The pH of a solution can be determined using pH indicators, pH meters, or pH test strips.

pH indicators are substances that change color depending on the pH of the solution. By comparing the color change to a color chart, the pH can be determined.
pH meters are electronic devices that measure the voltage or potential difference between a pH electrode and a reference electrode. The pH value is then displayed on the meter.
pH test strips are small strips of paper or plastic that are impregnated with pH indicators. By dipping the strip into the solution and comparing the color change to a color chart, the pH can be determined.

$p H = - log [H 3 O +] "> p H = - log [H 3 O +]$ .

0.055 M

[H3O+] = 5.5 X 10-2 M

pH = -\log(5.5 X 10-2) = 1.26
