How does bicarbonate indicator works?
Bicarbonate indicator works by changing color in response to the pH level of a solution. When added to a solution, the indicator changes color based on the amount of bicarbonate ions present, which can give an indication of the solution's pH level. This color change is due to the property of the indicator molecule to shift its absorbance spectrum based on the pH of the solution.
Is sodium bicarbonate an indicator?
No, sodium bicarbonate is not an indicator. It is a chemical compound commonly used for its buffering and antacid properties. Indicators are substances that change color in response to changes in pH levels.
What is a bicarbonate indicator?
A bicarbonate indicator is a substance that changes color in the presence of bicarbonate ions, like phenolphthalein or bromothymol blue. It is commonly used in titrations to determine the endpoint when bicarbonate ions are being neutralized.
What difference would you expect to see in the bicarbonate indicator in beakers A and B if beaker A had pumped air and beaker B had blown air in it?
well beaker b will have carbon in it as air is breathed in from the mouth, so the indicator will turn yellow! but on the other hand as the beaker A has pumped air in it there is no trace of carbon, so the indicator will turn red!
What is the colour of bicarbonate of soda added to universal indicator?
When bicarbonate of soda is added to universal indicator, it typically turns the solution a blue or purple color. This indicates a basic pH level.

What color does bicarbonate indicator change to?
Bicarbonate indicator changes color from orange-yellow to red when exposed to carbon dioxide. This change is due to the formation of carbonic acid, which shifts the pH of the solution causing the indicator to change color.

When bicarbonate of soda is added to universal indicator, it typically turns the solution a blue or purple color. This indicates a basic pH level.
What colour should sodium bicarbonate be in universal indicator?
Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
What color do alkalis turn universal indicator?
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
What color does the indicator turn when mixed with juice powder?
The answer will depend on which indicator is being used.
How do you prepare bicarbonate indicator?
To prepare a bicarbonate indicator, dissolve bromothymol blue powder (0.1g) in distilled water (100mL) to make a 0.1% solution. Adjust the pH slightly acidic by adding a few drops of dilute hydrochloric acid. The solution will turn yellow. It will act as an indicator turning blue in the presence of a base, indicating the presence of bicarbonate ions.
