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 universal indicator state the purpose for which this indicator is used?
Universal Indicator is used to test for the acidity of a solution, because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic.
How are universal indicators useful to scientist?
An Universal Indictator is more helpful because it shows the exact amount of acidity. Other indictators (example the red and blue litmus) just indicates whether or not the solution is acidic. The universal indicator gives you a specific color to which you can match a pH number therefore, telling you how acidic the soultion is.
How do you indicate that a solution is a alkaline solution or a base?
By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you>>>:)d
What is the name of the solution to test for acids or alkalis?
There are various ways to test for an acid and an alkali. For acidic solution: Litmus paper/ litmus solution --> red Phenolphthalein --> colorless Methyl orange --> pink Universal Indicator (changes color according to the strength of acid) --> red to yellow. For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
What substances turn universal indicator red?
all acidic substances with a PH below 7< turn the Universal indicator red due to their acidity.

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

What does it show if an aspirin solution has turned a universal indicator orange-red?
The aspirin solution is acidic; aspirin is the acetylsalicylic acid.
How do you indicate that a solution is a alkaline solution or a base?
By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you>>>:)d
What are acidic indicators?
Universal indicator or litmis paper
What does yellow indicate on the ph scale?
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.

For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
Why might a scientist prefer to use Universal Indicator rather than a different indicator like litmus?
Litmus only differentiates between acidic and alkaline solutions. It does not give an accurate value of the degree of acidity of alkalinity. Universal Indicator can help measure the pH of the given solution as it does not just change from red to blue and vice versa, but in solution has a range of colours.
What substances turn universal indicator red?
all acidic substances with a PH below 7< turn the Universal indicator red due to their acidity.
What is used as an indicator of whether a solution is acidic or basic?
pH strips are used to determine whether a solution is acidic or basic
What indicator has no color at all?
phenolphthalien when added to an acidic solution has a colourless indicator. but shows pink colour for basic solution.
