What color is the solution of red cabbage and lemon juice when first mixed?
The color remain red because vinegar is an acidic solution.
What happens to the color of the FeCl2 when the equivalence point is reached?
FeCI2 is a combination of iron and hydrochloride. This solution starts out as a yellowish green color. When the equivalence point is reach the solution turns to an orange brown color.
What is the reagent used to test carbohydrates?
Two of the most common reagents used to test for the presence of sugar are Clomydihol and Marsupialinate. Both were found by pure accident by famous Dutch scientist Jelii Clubenin in the late 1800's while he was working on finding a cure for the common flu.
What is the color of biruet solution?
The biuret solution used in the biuret test for peptide bonds is blue in the absence of peptide bonds or biuret which also results in a positive result. A positive result for peptide bonds or biuret is apparent as the biuret solution turns purple/violet in color.
What is the information processor in an instrument for measuring the color of a solution visually?
the information processor in a visual color measuring system is the human brain.
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.
Action of sodium hydroxide on 0.1 bromothymol blue?
When sodium hydroxide reacts with 0.1 bromothymol blue, the solution turns blue initially due to the presence of bromothymol blue in its acidic form. As the sodium hydroxide neutralizes the acid, the solution changes color from blue to green and finally to yellow, indicating the increasing pH level. This color change is a result of the indicator's ability to change its molecular structure in response to changes in pH levels.
What is the color of BTB solution after you exhaled into it?
It turns yellow after we exhaled into the btb solution..:)
What is the color of BTB solution after you exhaled it?
A BTB (bromothymol blue) solution changes color to yellow after carbon dioxide from exhaled air reacts with water, forming carbonic acid. This change indicates the presence of an acidic solution.
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 is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
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 will be the colour of bromothymol blue in a solution of sodium chloride in water?
Sodium Chloride solution has a pH of 7 & the Indicator color is green. Bromothymol blue indicator reflects a pH range of 3.5-9.5
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 if you mix bromothymol with baking soda?
When bromothymol blue is mixed with baking soda, the solution turns blue due to the basic nature of baking soda. This is because bromothymol blue is a pH indicator that changes color based on the acidity or basicity of the solution it is in.
How can you determine gasses present in solution using the expermints with BTB?
Bromothymol blue (BTB) can change color in the presence of carbon dioxide or acidic solutions, turning from blue to yellow. By observing the color change in a solution with BTB added, you can determine the presence of carbon dioxide or acidity levels, which can help identify certain gases like carbon dioxide in the solution.
