Yellow acidic form (left) and blue basic form (right) of bromothymol blue. [4] Bromothymol blue is sparingly soluble in oil, but soluble in water, ether, and aqueous solutions of alkalis. It is less soluble in nonpolar solvents such as benzene, toluene, and xylene, and practically insoluble in petroleum ether. [5]
Additives are used for many purposes but the main uses are: Acids Food acids are added to make flavors "sharper", and also act as preservatives and antioxidants. Common food acids include vinegar, citric acid, tartaric acid, malic acid, folic acid, fumaric acid, and lactic acid.
Solution: The main components of a universal indicator, in the form of a solution, are thymol blue, methyl red, bromothymol blue, and phenolphthalein. This mixture is important because each component loses or gains protons depending upon the acidity or alkalinity of the solution being tested. It is beneficial to use this type of universal ...
Inverted sugar syrup – (also called invert syrup) is an edible mixture of two simple sugars – glucose and fructose – that is made by heating sucrose (table sugar) with water and acid. [7] Kuromitsu – a Japanese sugar syrup, literally "black honey", it is similar to molasses, but thinner and milder
OF-glucose deeps contain glucose as a carbohydrate, peptones, bromothymol blue indicator for Hugh-Leifson's OF medium or phenol red for King's OF medium, and 0.5% agar. To perform the OF-glucose test, two tubes of OF-glucose medium are inoculated with the test organism.

Thymol blue (thymolsulfonephthalein) is a brownish-green or reddish-brown crystalline powder that is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions.
They are red in acidic solutions and blue in basic. Anthocyanins can be extracted with water or other solvents from a multitude of colored plants and plant parts, including from leaves ( red cabbage ); flowers ( geranium , poppy , or rose petals); berries ( blueberries , blackcurrant ); and stems ( rhubarb ).
