pH indicator is a base of any chemical reaction through which we determine the alkalinity and acidity of a chemical or a reagent. Emphor LAS provides trusted and the most precise pH indicators in UAE.
A pH indicator also popularly known as acid-base indicator is a compound that changes color in solution over a precise range of pH values. Only a small amount of indicator compound is needed to produce a visible color change.
A pH value is determined from the negative logarithm of the concentration and is used to indicate the basic, acidic or neutral character of any substance. They are added to numerous solutions to determine the pH values of chemicals and reagents in the laboratory. While the liquid form of pH indicators is typically added directly to chemical solutions, the paper form is dipped into solutions and the colour pattern is correlated against a colour/pH key. When used as a dilute solution, a pH indicator does not have a significant impact on the acidity or alkalinity of a chemical solution.
The math of pH indicator is pretty simple to understand, A pH less than 7 specifies an acidic solution and a pH greater than 7 specifies a basic solution. Eventually, the pH value indicates how much H+ has separated from molecules within a solution. The lower the pH value, the higher will be the concentration of H+ ions in the solution and stronger will be the acid. Similarly, the higher the pH value, the lower will be the concentration of H+ ions in the solution and the weaker will be the acid.
Some indicators change from one color to another, while others change between colored and colorless states. pH indicators are usually weak acids or weak bases. Many of these molecules occur naturally.
Plants contain pH indicators naturally, these molecules include red cabbage leaves, rose petal flowers, blueberries, rhubarb stems, hydrangea flowers, and poppy flowers. Litmus is a natural pH indicator derived from a mixture of lichens.
