What is used to test if something is acidic?
A universal indicator or pH paper can be used to test if something is acidic. This test is based on a color change in the indicator or paper when it comes into contact with acidic substances.
What is the pH indicator in nutrient agar?
None
How do you detect the equivalence point in acidic medium?
In acidic medium, the equivalence point can be detected using an acid-base indicator that undergoes a color change at the pH corresponding to the equivalence point. Alternatively, a pH meter can be used to monitor the pH of the solution during the titration, with the equivalence point identified as the point of maximum change in pH.
Explain the purpose of the phenol red in the medium?
To determine if a bacterium can ferment a particular carbohydrate and determine the end products of that fermentation
What is the material used to remove an indicator from a neutralized solution how does this work?
it is universal indicator with mixture of alkali
How do you determine the indicator constant?
The indicator constant is typically determined experimentally by monitoring the change in the indicator's color as the pH of the solution changes. The pH at which the color change occurs is the indicator constant. This value can also be found in literature references for commonly used indicators.
What is phenolphthalein?
it is a agar medium for Microbiology containing phenolphthalein biphosphate. It is used in Petri plates and detects the phosphatase character of microbial colonies but requires final addition of alkali to color the phenolphatlein and the color rapidly fades.
What is used as an indicator of whether a solution is acidic or basic?
pH strips are used to determine whether a solution is acidic or basic
Why is litmus used as an indicator?
Litmus paper can be used to determine if a solution is acidic or basic
What bromothymol blue is used for?
It is used as a pH indicator. It will turn yellow and green in the presence of more acidic situations.
Is alcohol neutral indicator?
No, alcohol is not a neutral indicator. It is a type of chemical compound that can act as a solvent or be used as a disinfectant. Neutral indicators are substances that change color at a specific pH to indicate the acidity or alkalinity of a solution.
What is the colour of lemonade when pH indicator is added?
When a pH indicator is added to lemonade, the color change depends on the specific indicator used. Most commonly, lemonade, which is acidic due to its citric acid content, will turn a pH indicator like phenolphthalein colorless, as it remains in the acidic range (pH below 7). However, if a pH indicator like bromothymol blue is used, it may turn yellow, indicating the acidic nature of the lemonade. Overall, the lemonade will appear in shades indicative of its acidity, typically yellow or colorless, depending on the indicator.
