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 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 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.


What happens when you mix bromothymol blue and calcium chloride?

Well, honey, when you mix bromothymol blue and calcium chloride, you get a chemical reaction that forms a precipitate. The bromothymol blue changes color from blue to yellow, thanks to the acidic environment created by the calcium chloride. So, in short, you get a colorful chemistry party that's sure to impress your inner science geek.


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.
