Does a stronger acid make indicator paper red or orange?
It makes it red.
Is methyl orange an indicator?
Phenolphtalein remains colourless in acids, but turns pink in bases Methyl Orange indicator turns pink in acids and yellow in bases Acids turn litmus paper red bases turn litmus paper blue irrespective of which colour litmus paper is used
An indicator does which one of the following in the presence of acids and bases?
Indicators can be used to determine if a substance is a acid or a base because of the reaction that occurs between the substance and the indicator. This creates a color change in the indicator (depending on which indicator you use). If it is a universal indicator, the substance may change from deep red to violet. If it is a litmus indicator, it will only turn either red or blue.
Is an indicator color change an acid or base?
depends on the indicator used. in case of red litmus... changes to blue for basesand no change in acids blue litmus - changes to red in acids, no change in bases phenolpthelin - changes to pink in bases, no change in acid methyl orange - changes to red in acids and yellow golden in bases
What color will acids and bases turn litmus paper?
Acid turns it in red, while base will turn it blue.

What is use of indicator?
Indicator is a process which is used to find out the substanceis acid,base and salt. example: litmus paper and termuric both are natural indicator. example of artificial indicator: mithyl orange and phenolphtaceil

What are two examples of natural indicator of acid and bases?
Red litmus paper and blue litmus paper. Blue litmus paper turns red in the presence of an acid and red litmus paper turns blue in the presence of an alkali.

What is a indicator of acid?
All acidic solutions are colourless in phenolphthalein, pink in methyl orange solution and turns blue litmus paper into red.
What does an universal indicator tell you about an acid that litmus doesn't?
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
What color will acids and bases turn litmus paper?
Acid turns it in red, while base will turn it blue.
What colour is produced when universal indicator is added to acetic acid?
weak acid = orange/yellow
What kind of indicator paper turns red in acid?
Litmus
How can you test for an alkaline or acid?
With a universal indicator or with litmus paper.
