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 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.
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.
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.
Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
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.
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.
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.
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

An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
Bromothymol blue is used in scientific experiments as a?
pH indicator to visually determine the acidity or basicity of a solution. It changes color from yellow to blue depending on the pH of the solution.
