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.
What else can I help you with?
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 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 household items contain bromothymol blue?
Bromothymol blue has no household uses.
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.
What type of compound turns bromothymol blue in greenish?
Bromothymol blue is a pH indicator that turns greenish in solutions with a pH around neutral, typically between 6.0 and 7.6. Compounds that create this range, such as weak acids or weak bases, can result in a greenish color when mixed with bromothymol blue. For example, a solution containing a weak acid like acetic acid or a weak base like sodium bicarbonate can cause this color change.
What colour is bromothymol blue in water?
Bromothymol blue is blue in neutral or basic solutions, and yellow in acidic solutions.
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 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.
What is the pH when Bromothymol blue turns green?
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).
What is the chemical equation for bromothymol blue?
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.
What colour is bromothymol blue?
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).
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.
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.
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.
Why does bromothymol blue stay blue in sunlight?
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.
What happens when you mix SODIUM HYDROXIDE and Bromothymol blue?
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.
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
