Litmus solution is purple dye which is is extracted from?
Litmus solution is obtained from lichens. It is used to test whether the solution 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.
What color range did the substance show when tested with the indicator paper?
Indicator paper is a common name for litmus paper. Litmus paper tests pH. The color range is red to purple, when red is very acidic (pH of 1) and purple is very basic (pH of 14). In between the spectrum are the other pH values. Green is neutral (a pH of 7). Yellow and orange are acids also, ranging from a pH of 2-6. Teal and blue are bases, with pH ranging from 8-13. Hope this helps!
What effect does and alkali have on an universal indicator?
It turns the universal indicator purple or blue.
How can you identify an acid and an alkali?
You identify acids and alkalis using indicators. Indicators are substances which turns a particular colour for acids and another for bases. E.g. litmus, (acid-red, alkali-green) and phenolphthalein. Indicators have a certain pH value. You can only use a particular indicator of a suitable pH value for a particular acid-base reaction
What is the color of purple bougainvillea indicator if the substance is acid?
acidic - magenta basic - no colour change
How do you make an indicator?
If you want to make a purple indicator, just cut up some purple cabbage and cook it in boiling water for about 5-10 minutes or until it turns purple. When you place another substance in it it will turn pink if it is acidic, and if if turns a green it is a base...... if it stays purple the substance is neutral.
Why does cabbage juice work as an indicator?
put small pieces of purple cabbage in hot water and stir it and leave it for 20 min and take only water. if indicator turns substance red it is acidic ,if blue then basic if no change then neutral
What does universal indicator tell you about a material?
the universal indicaicator tells you the pH of a substance. Green nuetral pH7 Below pH 7 is acidic,red Above pH7 is alkalie blue/purple
What substance does purple cabbage indicator actually test for?
it tests for carbonic acid
Litmus solution is purple dye which is is extracted from?
Litmus solution is obtained from lichens. It is used to test whether the solution is acidic or basic.
How do you test for alkaline?
You could test the pH of the substance with UI (universal indicator) paper, or some other indicator. If the pH is <7 or the paper is red/orange/yellow, then its acidic. If the pH is >7 or the paper is blue/purple, then its alkaline. In-between is neutral (green).

How is a indicator used?
If you mean a universal indicator, it is used to detect if a chemical is acid, alkali or neutral. It changes colour to show the chemicals position on the pH scale A universal indicator turns red at pH1 (Very acidic), orange at pH4 (Fairly acidic), yellow at pH6 (Not very acidic) and green at pH7 (Neutral). It turns more dark blue as it gets to pH10 (Quite Alkaline) and more to purple by ph12 (Even more alkaline) and to a dark purple by pH14( Very Alkaline).
What color does yamada indicator turn in?
Turn in what? it depends. The colors vary. Green is neutral. The more acidic a substance is the more red it becomes, but between the green and red are colors like pink, orange, yellow but red means most acidic. If its a base it starts to turn blue and the more alkaline it has begins to turn purple.
What color is more acidic blue or purple?
Between blue and purple, blue is more acidic than purple.
