What else can I help you with?
One indicator that changes colour in an acid and alkali solution?
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
Universal indicator is a solution that changes what in an acidic or alkali solution?
Universal indicator doesn't change anything in an acidic or alkali solution. All universal indicator does is show how acidic or alkaline a solution is (red being acidic, green being neutral and blue being alkali)
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
What colour does when universal Indicator goes in alkali?
When universal indicator is added to an alkali, it typically turns dark purple or dark purple-blue in color. This indicates a high pH level in the solution.
What colour will universal indicator paper go if dipped into ammonia solution?
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
What is the material used to remove an indicator from a neutralized solution how does this work?
it is universal indicator with mixture of alkali

How does a acid-alkali indicator indicates?
The pH of a solution.

What would you use to show when an acid has completely reacted with an alkali?
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
What colour will universal indicator paper go if dipped into ammonia solution?
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
What colour do you get if you mix litmus solution and alkali?
If you mix litmus solution with an alkali, the litmus solution will turn blue. Litmus is a pH indicator that turns red in acidic solutions and blue in alkaline solutions.
What colour an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.
What colour does universal indicator go in a alkali?
Universal indicator turns shades of blue or purple in an alkali.
What is an indicator acid or alkali?
An indicator is a substance that changes color in the presence of an acid or alkali. Common indicators include litmus paper (blue for alkaline, red for acidic), phenolphthalein (colorless in acidic solutions, pink in alkaline solutions), and universal indicator solution (multiple colors to indicate pH level).
