What chemical indicators are and what they are used for?
Chemical indicators are substances that change color in response to specific chemical conditions, such as pH level, presence of certain ions, or concentration of a particular substance. They are commonly used to visually identify the presence or absence of a chemical reaction or to monitor changes in chemical properties in experiments or industrial processes.
What is a chemical dye that changes color based on the pH of a solution called?
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
What is chemical indicator dye?
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
What is the name of the pH indicator used in microbiology?
The pH indicator commonly used in microbiology is phenol red. It changes color depending on the pH of the solution, allowing for easy visualization of pH changes in bacteria cultures.
Ways in which chemical reactions can be identified?
Chemical reactions can be identified by changes in color, temperature, or the formation of a precipitate. Additionally, observing the release or absorption of gas, or changes in pH can also help identify chemical reactions. Analyzing the starting materials and products using techniques like spectroscopy or chromatography can provide further evidence of a chemical reaction.

What is a pH curve?
A pH curve is a graph that shows how the pH of a solution changes as a particular chemical reaction or process occurs. It typically displays the pH on the y-axis and the volume of titrant added on the x-axis to help visualize how the pH of the solution changes with the addition of an acid or a base. pH curves are commonly used in acid-base titrations to determine the equivalence point and identify the unknown concentration of a solution.
What substancces uses universal indicator paper to identify them?
Universal indicator paper can be used to identify substances that have a pH in the range of 1 to 14. It changes color based on the pH level of the substance it comes into contact with, allowing for quick and easy identification of acids, bases, or neutral solutions.

What stimulate the chemoreceptor?
Chemoreceptors are stimulated by changes in the chemical composition of the environment, such as changes in the concentration of oxygen, carbon dioxide, and pH levels. These receptors are responsible for detecting and transmitting information about these chemical changes to the brain, which helps regulate important physiological processes like breathing and blood pH.
Why is phenolphthalein used as an indicator in chemical experiments?
Phenolphthalein is used as an indicator in chemical experiments because it changes color depending on the acidity or alkalinity of a solution. This makes it easy to visually determine the endpoint of a reaction or the pH level of a solution.
How does the pH of juice change with time How does temperature affect the rate of chemical changes?
The pH of juice can change over time due to chemical reactions such as oxidation and fermentation. Higher temperatures generally increase the rate of chemical reactions, so temperature can affect the rate at which the pH of juice changes. Higher temperatures can lead to faster degradation of components in juice, which can impact its pH.
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.
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.
