WebA pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or … WebTest tubes containing solutions of pH 1–10 colored with an indicator. In chemistry, pH ( / piːˈeɪtʃ / ), also referred to as acidity, historically denotes "potential of hydrogen " (or "power of hydrogen"). [1] It is a scale used to specify the acidity or basicity of an aqueous solution.

WebAcid-Base Titrations Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change. WebThe indicator changes color from acid to base when it’s in the range of pH values. The acid form can only be seen at the highest pH, the base form can only be seen at the lowest. Since the indicator doesn’t change color at certain pH levels, it’s not sensitive to changes outside of its range. Selection of indicator in acid base titration
