What was the role of the water test tube in each phase?
In the phase where the bromothymol blue solution was added and the lamp was switched on, the water test tube served as a control, helping to compare the change in color of the bromothymol blue solution with that of pure water when exposed to light. In the phase where the elodea was added and the lamp was switched on, the water test tube acted as a comparison point to show any changes in the color of the bromothymol blue solution due to the presence of the plant.
What color do pinto bean change when using bromothymol blue is used?
When bromothymol blue is used with pinto beans, the color change indicates the pH of the solution. In an acidic environment, bromothymol blue turns yellow, while in a neutral to slightly alkaline environment, it appears green or blue. Therefore, if pinto beans are tested in a solution with bromothymol blue, the color change will reflect the acidity or alkalinity of the solution surrounding the beans.
What is the action of potassium hydroxide on 0.1 bromothymol blue?
The color is dark blue.
What happens when bromothymol blue is put in a neutral substance?
When bromothymol blue is placed in a neutral substance, such as pure water with a pH around 7, it remains a greenish color. This is because bromothymol blue is a pH indicator that changes color based on acidity or basicity; it appears yellow in acidic solutions (pH < 6) and blue in basic solutions (pH > 7). Thus, in neutral conditions, it does not undergo any significant color change.
Is biuret solution the same as bromothymol blue?
No, biuret solution and bromothymol blue are not the same. Biuret solution is a chemical reagent used to detect the presence of proteins, indicated by a color change to purple when proteins are present. In contrast, bromothymol blue is a pH indicator that changes color based on acidity, shifting from yellow in acidic conditions to blue in alkaline conditions. They serve different purposes in laboratory settings.
What happened when sulphuric acid add in bromothymol blue solution?
When sulfuric acid is added to bromothymol blue solution, the color changes from blue to yellow. This is due to the decrease in pH caused by the addition of the acid. Bromothymol blue is a pH indicator that changes color in response to changes in acidity or alkalinity.
What happens when you mix NaOH and Bromothymol blue?
When NaOH is added to Bromothymol blue, the solution turns blue due to the increase in pH caused by the base. This color change occurs because Bromothymol blue is a pH indicator that changes color in response to pH levels.
How do bases change the color of bromothymol?
Bases change the color of bromothymol blue indicator from yellow to blue. This color change occurs because in acidic conditions, bromothymol blue appears yellow, while in basic conditions, it shifts to blue.
What is the color of bromothymol?
Bromothymol is a pH indicator that can appear yellow in acidic conditions and blue in alkaline conditions.
What was the role of the water test tube in each phase?
In the phase where the bromothymol blue solution was added and the lamp was switched on, the water test tube served as a control, helping to compare the change in color of the bromothymol blue solution with that of pure water when exposed to light. In the phase where the elodea was added and the lamp was switched on, the water test tube acted as a comparison point to show any changes in the color of the bromothymol blue solution due to the presence of the plant.
What would be the color of bromothymol blue in dilute nitric acid?
Bromothymol blue would appear yellow in dilute nitric acid.
Colour of nitric acid in 0.1 bromothymol blue?
Nitric acid is a strong acid and will turn bromothymol blue to yellow in color because it contains protons that can react with the indicator, causing it to change color.
What is the action of sodium chloride on 0.1 bromothymol blue?
Sodium chloride will not have any significant impact on bromothymol blue since it is a neutral compound that does not affect the pH indicator properties of bromothymol blue.
Why does bromothymol blue changes color into green?
it changes color because by the human air that u blow it.
What happens when you mix TAP WATERand Bromothymol blue?
When mixed with tap water, bromothymol blue will change color depending on the acidity of the water. In acidic conditions, it will turn yellow; in neutral conditions, it will be green; and in basic conditions, it will be blue. This color change is due to bromothymol blue's pH-sensitive properties.
What is the action of potassium hydroxide on 0.1 bromothymol blue?
The color is dark blue.
Colour of hydrochloric acid in bromothymol blue?
Hydrochloric acid turns bromothymol blue yellow because the acid changes the pH of the solution, causing the bromothymol blue indicator to shift its color toward the yellow end of the spectrum.
