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 will be the colour if bromothymol blue placed in a table salt solution?

Bromothymol blue is a pH indicator that transitions from yellow in acidic solutions to blue in basic solutions. In a neutral solution, such as a table salt solution (which is typically neutral), bromothymol blue will appear green, as it sits between its yellow and blue color states. Thus, the color of bromothymol blue in a table salt solution would be green.


What does photosynthesis have to do with the use of Bromothymol Blue?

Bromothymol blue is an indicator which changes colour in the presence of an acid. When carbon dioxide mixes with water it produces carbonic acid (soda water). A pretty common experiment involves putting a respiring organism in water mixed with bromothymol blue, the water should turn yellow as the organism takes in oxygen and produces carbon dioxide. The indicator can be changed back to its original blue colour by removing the carbon dioxide from the water, i.e. putting in a plant to run photosynthesis - drawing out the carbon dioxide to produce oxygen.


How does the pH indicator bromothymol blue measure cellular respiration?

He can use a chemical reaction when it is mixed with CO2


What color would you expect bromothymol blue to be when pure water added?

Bromothymol blue is a pH indicator that appears yellow in acidic solutions and blue in basic solutions. When added to pure water, which has a neutral pH of around 7, bromothymol blue would typically appear green, as it transitions between yellow and blue around this pH level. The exact shade may vary slightly depending on the concentration of the indicator and the specific conditions of the water.
