Colour chart of universal indicator colours at different pH values. A 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.Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the Arrhenius model.Normally, the indicator causes the color of the solution to change depending on the pH. When you find the number associated with the color on the strip, you’ll have your pH reading. As you vary the molarity of the solution the pH changes and the color of the chosen indicator changes accordingly. At a neutral pH (approx.

The exception to this rule is phenolphthalein, which is colorless when outside of its range. At pH 7, the halfway point, there is a balance between acidity and alkalinity, the solution is neutral. The pH range and color changes for each indicator are as follows: phenolphthalein, 8.0–10.0, colorless-magenta-colorless, [1] J. C. Kotz, P. M. Treichel, and J. R. Townsend, Chemistry & Chemical Reactivity, 8th ed. Just as paint stores have pages of color chips, soil scientists use a book of color chips that follow the Munsell System of Color Notation (www.munsell.com). More on this is provided at Interpreting soil colour; Where a Munsell Chart is not available, simple names as listed in the above triangle can be used. Because the reaction of hydrochloric acid with water is in a 1:1 ratio, the concentration of the H+ ions is equal to the molarity of the solution, so the pH of hydrochloric acid in terms of molarity is . The value of the pH is also shown. The colour is matched with the standard colour chart (as shown in Fig. ... neutral pH 7 is indicated by green. Wait approximately 30 seconds and compare the resulting color change with the color chart. At a higher pH, around 5, the color turns into a darker purple.
