Bromothymol blue

C27H28Br2O5S, ACS 95%, CAS : 76-59-5

Bromothymol Blue, a pH indicator, has several applications in secondary school studies. In biology, it is used to demonstrate the process of photosynthesis, where it changes color in the presence of carbon dioxide. Students can observe the color change in a solution containing Bromothymol Blue when carbon dioxide is added or removed. In chemistry, Bromothymol Blue is employed to determine the pH of a solution, as it changes color depending on the acidity or alkalinity. This allows students to understand the concept of pH and perform simple acid-base titrations. The use of Bromothymol Blue enhances students' understanding of photosynthesis, chemical reactions, and pH measurements.

溴百里酚藍是一種 pH 指示劑，在中學研究中有多種應用。 在生物學中，它被用來展示光合作用的過程，在二氧化碳存在的情況下它會改變顏色。 學生可以觀察添加或移除二氧化碳時含有溴百里酚藍的溶液的顏色變化。 在化學中，溴百里酚藍用於確定溶液的 pH 值，因為它會根據酸度或鹼度改變顏色。 這使學生能夠理解 pH 值的概念並進行簡單的酸鹼滴定。 溴百里酚藍的使用增強了學生對光合作用、化學反應和 pH 測量的理解。
