2. Next, in order to begin the acidity or alkalinity test, tear off one PH strip and dip into the liquid. You may also drip a sample of liquid onto a litmus strip or press a litmus strip onto the damp sample. It depends on your desired way to perform the test.
3. The strips will change color within 15 seconds to be matched with the pH scale color chart.
