If you are testing with Universal Indicator or the Litmus Test it will turn red.
What is acid base indicator?
An acid base indicator is a chemical substance that has the ability to change color depending on the pH.
What color does yamada indicator turn in presence of an acid?
Presence of what??? Turn in what? it depends. The colors vary. Green is neutral. The more acidic a substance is the more red it becomes, but between the green and red are colors like pink, orange, yellow but red means most acidic. If its a base it starts to turn blue and the more alkaline it has begins to turn purple.
What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What is the solution of NaOH in methyl orange indicator?
The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.
Does ethanoic acid turn universal indicator purple?
No, ethanoic acid (acetic acid) is a weak acid and will turn universal indicator a different color depending on its pH level. It will likely turn universal indicator red or orange indicating acidity.
What color does the indicator paper turn if the substance is a strong acid?
If you are testing with Universal Indicator or the Litmus Test it will turn red.
What is the result for acid and alkaline respectively when they're tested with red rose indicator?
If red rose indicator is used, acid will turn the indicator red, while alkaline solutions will turn the indicator green.
Does citric acid turn red using a universal indicator?
Citric acid typically does not turn red when tested with a universal indicator. Citric acid is a weak acid and will likely show a color close to neutral or slightly acidic on the indicator scale.
What colour will universal indicator turn when acid is mixed with alkali?
Universal indicator will turn green when an acid is mixed with an alkali. This green color indicates a neutral pH level which is achieved when the acid and alkali have neutralized each other.
What color when acid is put on china rose indicator?
When acid is put on china rose indicator, the indicator will turn red in color. This color change indicates that the solution is acidic. China rose indicator contains anthocyanin pigments that change color based on the pH of the solution.
What color would hydrochloric acid pH 1 turn universal indicator?
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
What color does citric acid turn universal indicator?
Citric acid is a weak acid, so it will turn universal indicator to a color range between orange and red, indicating an acidic pH.
What color does vinegar turn when dipped in acid?
When vinegar, which is slightly acidic itself, is further dipped in a stronger acid such as hydrochloric acid, it does not change color but rather reacts chemically to produce effervescence (bubbling) due to the release of carbon dioxide gas.
What colour would the red petal indicator be in a solution of sulphuric acid?
The red petal indicator would likely turn blue in a solution of sulphuric acid because sulphuric acid is a strong acid that would cause the indicator to change color.
What color will lemonade turn into when red cabbage indicator is in it and why?
Lemonade will turn pink when red cabbage indicator is added to it. This color change is due to the red cabbage indicator being sensitive to pH levels. The acidity of the lemonade will cause the red cabbage indicator to change color to pink.
What colour would the red petal indicator be in sulphuric acid?
The red petal indicator would turn blue in sulfuric acid. This color change occurs due to the strong acidity of sulfuric acid causing a shift in the pH level, resulting in the red petal indicator changing color.
