Tropaeolin O is a synthetic dye that belongs to the tropaeolin family of dyes. It is also known as Acid Orange 10 or Orange G. Tropaeolin O is commonly used as an acid-base indicator, which means it changes color depending on the pH of a solution. It is a water-soluble dye and has a bright orange color.
Tropaeolin O is often employed in laboratory settings as an indicator in various chemical reactions and titrations. It has a transition range between approximately pH 1.2 and 4.2, where it changes color from orange to pink. This transition range makes it useful for determining the endpoint of acid-base titrations.
In addition to its laboratory applications, Tropaeolin O has been used in the textile industry to dye fabrics and in the production of inks and paints. However, its usage in these industries has decreased over time due to environmental concerns and the availability of alternative dyes.
