:Bleu de bromothymol
Description :
Bleu de bromothymol est un indicateur de pH couramment utilisé dans diverses applications chimiques et biologiques. C'est un colorant synthétique qui présente un changement de couleur distinct selon l'acidité ou l'alcalinité d'une solution. Dans des conditions acides, il apparaît jaune, tandis que dans des conditions neutres à légèrement basiques, il passe au vert, et dans des environnements plus alcalins, il devient bleu. Cette caractéristique le rend utile pour surveiller les changements de pH lors de titrations et d'expériences biologiques. Le composé a une formule moléculaire de C27H28Br2O5S et un poids moléculaire d'environ 624,4 g/mol. Bleu de bromothymol est soluble dans l'alcool et légèrement soluble dans l'eau, ce qui peut limiter son utilisation dans certaines applications aqueuses. Il est souvent utilisé dans des environnements de laboratoire, en particulier en microbiologie et en biochimie, pour évaluer le pH des milieux de culture. De plus, il est non toxique et sûr à utiliser dans des contextes éducatifs, ce qui en fait un choix populaire pour des démonstrations et des expériences impliquant la chimie acido-basique.
