Litmus paper or phenolphthalein.
What is the reaction with litmus paper in carbon?
Carbon (C) has any influence on litmus paper.
How can you test for acids and bases?
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
Can You Drink something if you put litmus paper in there first?
The reaction of a litmus paper is contained solely on the litmus paper. The liquid/solution is unchanged when introduced to the paper. It's not advised to drink the liquid/solution if it's inedible, but litmus paper won't affect it.
Litmus paper and phenolphthalein are examples?
the actual answer is that litmus is an example of an indicator because... if for example you dip a blue litmus paper into lime juice (an acid) the litmus paper will turn red because it indicates that its an acid or......... if you dip a red litmus paper into a base it will turn blue because it indicates that it is a base..... so the answer is because it indicates if its an acid or basep.s. if the blue paper turned red---- indicates its a baseif the red paper turned blue ----- indicates its a acid or the other way around forgot... :/hopes this helped........ :)))))))))))
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.
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 colour does tomato juice turn phenolphthalein?
The litmus paper turns Orange. Because it has a pH of 4 so it's orange. :)
Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
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 is the reaction with litmus paper after boiling the water and ferric chloride mixture?
The Blue Litmus paper will turn into Red, while the Red litmus paper will retain its color. So it only indicates that the said mixture is an acid.
What do you call Its turns blue litmus paper to red?
