Two commonly used indicators are bromothymol blue and phenolphthalein. Bromothymol blue is typically used in acid-base titrations, changing from yellow in acidic solutions to blue in alkaline conditions. Phenolphthalein, on the other hand, is colorless in acidic solutions and turns pink in alkaline environments, making it another popular choice for similar applications. Both indicators help visualize pH changes during chemical reactions.
What else can I help you with?
Is bromthymol blue living?
No, bromthymol blue is not a living organism. It is a chemical compound commonly used as a pH indicator in laboratories to detect changes in acidity or alkalinity in a solution.
How one might use bromthymol blue and phenolphthalein to test the ph of water in a swimming pool?
Having just done an experiment in class I think I can answer this. In a test tube collect some swimming pool water then add some bromthymol blue and phenolphthalein and using pH paper dip it in the solution to determine the pH.
What is commonly used natural indicator?
natural indicators can be used to detect whether a given substance is an acid or base.It can be easily available in our homes too. And you can prepare it too.They do not have harmful affects .so they should be used instead of chemical indicator which may some time be harmful.

What are absorbing indicators?
Absorbing indicators are substances that can absorb light at a specific wavelength and then emit light at a longer wavelength. These indicators are commonly used in chemistry for analyzing the presence or concentration of certain compounds in a solution based on the color change they produce.
Is bromthymol blue living?
No, bromthymol blue is not a living organism. It is a chemical compound commonly used as a pH indicator in laboratories to detect changes in acidity or alkalinity in a solution.
Can bromthymol blue be used as a stain for a cheek cell in compound microscopy?
No, bromthymol blue is typically used as a pH indicator, not a stain for cells. To stain cheek cells for microscopy, dyes like methylene blue or eosin are commonly used as they specifically bind to cellular components and enhance contrast for better visualization.
Can reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Phenolphthalein is typically used as a base indicator as it changes color in the presence of bases. Bromthymol blue can be used as both an acid and a base indicator, with different color changes for each.
Why did we use bromthymol blue in this experiment?
Bromthymol blue was used in the experiment as an indicator to monitor changes in pH. It changes color in response to pH changes, turning from blue to yellow in an acidic environment and blue to green in a neutral to basic environment. This allows us to visually track any changes in pH during the experiment.
What are the indicators in iodometry?
Indicators commonly used in iodometry include starch, which forms a blue-black complex with iodine, and potassium iodide, which reacts with iodine to form a yellow-brown color. These indicators help in detecting the endpoint of the iodometric titration.
What are some commonly used indicators?
Left, and Right.
How one might use bromthymol blue and phenolphthalein to test the ph of water in a swimming pool?
Having just done an experiment in class I think I can answer this. In a test tube collect some swimming pool water then add some bromthymol blue and phenolphthalein and using pH paper dip it in the solution to determine the pH.
What is the function of bromthymol blue in CO2?
Bromthymol blue is used as an indicator to detect the presence of carbon dioxide (CO2) in a solution. It changes color in the presence of acidic conditions, which can indicate the presence of CO2 as it forms carbonic acid when dissolved in water.
What substance is used as an acid-base indicator?
Phenolphthalein, Metyl Orange, Methyl Red, Thymol Blue and Bromothymol Blue are some of the commonly used acid-base indicators. The property of such indicators should be the capability of showing a distinct chemical change with respect to a particular pH value.
What are some indicators?
Indicators are chemicals that change color in the presence of an acid or a base. The most commonly used indicator is phenophthalein.
What are some indicators of acids?
Methyl Red, methyl orange, bromophenol blue, phenolphthalein, thymolphthalein, bromocresol green, bromothymol blue are all used as acid base indicators.
What is used to indentifiy bases and acids?
Acid base indicators are used to identify acids and bases. Among the common indicators are;PhenolphthaleinMethyl redMethyl orangeBromothymol blue
