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.
Bromothymol blue has no household uses.
If the red litmus paper stays red, then the object tested may be either an acid or a neutral substance. The substance must be tested on blue litmus paper. if the blue paper stays blue, then it is neutral. If it turns red, then it is an acid.
No, bromothymol blue is not typically used in blue food coloring. Blue food coloring usually contains synthetic colorants such as Brilliant Blue FCF (Blue 1) or Indigo Carmine (Blue 2), which are specifically approved for food use by regulatory agencies. Bromothymol blue is more commonly used as a pH indicator in laboratories and not intended for consumption.
The color is dark blue.
Hydrogen Chloride (HCl) is an acid. Bromothymol blue turns yellow as HCl is placed in it. Acids change the color of bromothymol blue from green-yellow, depending on whether it is a strong acid or a weak acid.
Bromothymol blue is blue in neutral or basic solutions, and yellow in acidic solutions.
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.
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.
The pH when Bromothymol blue turns green is around 6.0 to 7.6. At this pH range, the indicator changes color from blue (basic) to green (neutral).
The chemical equation for bromothymol blue is C27H28Br2O5S. It is represented by the organic dye with a blue color in its acidic form, yellow in its neutral pH state, and green in a basic environment.
Bromothymol blue is a pH indicator dye that is typically blue in alkaline conditions (pH > 7), green in neutral conditions (pH = 7), and yellow in acidic conditions (pH < 7).
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.
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.
Bromothymol blue stays blue in sunlight because it is a pH indicator that changes color based on the acidity of the solution it is in. In neutral or basic conditions, it appears blue, which is more stable in sunlight.
When sodium hydroxide is mixed with bromothymol blue, the solution turns blue due to the alkaline nature of sodium hydroxide. This indicates a basic pH level.
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
Bromothymol blue has no household uses.
