How does ph tester work
WebFeb 10, 2024 · PH test strips work by changing color. They use a technology called litmus paper. When litmus paper is dipped into a solution it changes color to show how acidic or alkaline the solution is. They are regularly used in homes to test the acidity/alkalinity of water, urine, and saliva. WebpH strips are pieces of paper that change color depending on the pH – the acidity or alkalinity – of a liquid. pH strips are a cheap and relatively accurate way of measuring the pH of any liquid, in our case urine. A strip of filter paper is soaked with different pH indicators (more on that later), allowed to dry and voila: pH strips.
