The word "Phenolsulfonphthalein" is a composite of several chemical compounds that end up forming a compound word. The word is spelled "fɛnoʊlˌsʌlfənfˈθaliɪn" in IPA phonetic transcription. The word is derived from phenol, sulfon, and phthalein. Phenol is the main compound, with sulfon and phthalein being secondary compounds. The unique spelling of "Phenolsulfonphthalein" can be attributed to the fact that it is an amalgamation of different words of various origins, which are combined to form a single word.
Phenolsulfonphthalein is a chemical compound that is primarily used as a pH indicator. It is a synthetic dye with the chemical formula C19H14O5S, and its systematic name is 3',3''-bis(phenylsulfonamido)-4',5'-dihydroxy-phenolphthalein.
Phenolsulfonphthalein is commonly used in laboratory settings to determine the pH level of a solution. It undergoes a color change from colorless to pink or purple under specific pH conditions. Typically, it transitions from colorless to pink when the pH is less than 6.8, and from pink to purple when the pH exceeds 7.6. This makes it useful in various applications, such as testing the pH balance of soil, water, and biological samples.
Due to its ability to easily detect changes in pH, phenolsulfonphthalein is also used in medical diagnostics and pharmaceutical research. In medicine, it has been historically employed as a renal function test to assess the efficiency of the kidneys in eliminating waste products. By monitoring the rate at which phenolsulfonphthalein is excreted by the kidneys, healthcare professionals can evaluate renal function. However, this application has largely been replaced by more advanced techniques.
Overall, phenolsulfonphthalein is an essential tool in pH testing, allowing for quick and accurate determination of acidity or alkalinity.
The word "Phenolsulfonphthalein" is derived from its chemical composition and the names of its constituent parts.
The term "Phenol" refers to the organic compound characterized by its hydroxyl (-OH) group attached to an aromatic carbon ring.
The term "Sulfon" stems from the sulfonic acid group (-SO3H), which is a functional group consisting of a sulfur atom bonded to three oxygen atoms and attached to the carbon chain.
"Phthalein" refers to a class of organic compounds that contain a phthalic acid moiety, which is a benzene ring with two carboxylic acid groups (-COOH) attached.
Therefore, "Phenolsulfonphthalein" is a compound that combines the phenol, sulfonic acid, and phthalein components.
