What is the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.
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.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
What is indicator in microbiology media and how it works?
An indicator in microbiology media is a substance that changes color or exhibits a visible change in response to specific conditions, such as changes in pH or the presence of certain metabolites produced by microorganisms. For example, phenol red is a pH indicator that turns yellow in acidic conditions, signaling fermentation by bacteria. These indicators help researchers identify and differentiate between microbial species based on their metabolic activities, aiding in the detection and enumeration of microorganisms in a sample.

What fruit and vegetable can you use as a pH indicator?
Red cabbage can be used as a pH indicator for a wide range of pH levels, showing different colors depending on the acidity or alkalinity of a substance. Similarly, beets can also be used as a pH indicator, turning different colors in acidic or basic solutions.
What creteria is used for chosing an indicator in acid base titration?
pH range of indicator should be in the rapid pH gradient.
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.
What is universal indicator state the purpose for which this indicator is used?
Universal indicator is a mixture of dyes that changes color in response to different pH levels. It is used to determine the approximate pH of a solution by observing the color change of the indicator when added to the solution.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.

What is used to determine the pH of an acid or base?
indicator
What is used to determine the pH of acid and bases?
A pH meter or pH indicator paper is commonly used to determine the pH of acids and bases. pH meters provide a numerical measurement of pH, while pH indicator paper changes color based on the pH level to give a visual indication.
What is the name of an indicator that measures pH?
Litmus paper goes red or blue in acids or universal indicator may measure some level of pH

Why can cabbage but not lettuce be used to create a pH indicator?
Cabbage contains a pigment called anthocyanin that changes color based on pH levels. Lettuce does not contain this pigment, so it cannot be used as a pH indicator.
