How do you prepare methyl orange indicator for titration?
To prepare methyl orange indicator for titration, dissolve 0.1g of methyl orange powder in 100mL of distilled water. This will give you a 0.1% solution of methyl orange which is suitable for use as an indicator in acid-base titrations.
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.
What colour is citric acid in universal indicator?
Citric acid is generally colorless in universal indicator. It is a weak acid, so it does not exhibit a strong color change in the indicator solution.
What colour does acid turn when added to universal indicator?
When acid is added to universal indicator, the indicator will typically change to shades of red, orange, or yellow, depending on the strength of the acid.
What colour does universal indicator turn in battery acid?
Universal indicator typically turns red in battery acid, indicating that the acid is highly acidic.
What is the indicator of acid?
The indicator of acid is baking soda.

What will an indicator do in the presence of an acid or base?
This indicator changes his color.
What colour does acid turn when added to universal indicator?
When acid is added to universal indicator, the indicator will typically change to shades of red, orange, or yellow, depending on the strength of the acid.
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 colour does citric acid turn an universal indicator?
Citric acid is a weak acid, so it would turn a universal indicator to orange or red.
What colour does universal indicator turn in battery acid?
Universal indicator typically turns red in battery acid, indicating that the acid is highly acidic.
How do you a prepare ferric alum indicator?
To prepare ferric alum indicator, dissolve 5-10 grams of ferric ammonium sulfate in 100 ml of distilled water. This solution will serve as the indicator for chloride ions, turning yellow in the presence of chloride ions.
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.
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.
