A universal indicator is a pH indicator that exhibits a gradual change in color to indicate the acidity or alkalinity of a solution. It can show a range of pH levels, typically from 0 to 14, with distinct colors corresponding to different pH values. Universal indicators are commonly used in laboratories and educational settings for pH testing.

What is dangerous about universal indicator?
yes i drank it once and i ended up in hospital for 3 weeks as universal indicator contains a poisonous chemical called methanol which is very harmful to the human body as well as any other animals. i now have partial blindness and it caused damage to the insides of my body. i have now realised that it was a very bad thing to do and no one should ever ever EVER drink chemicals from a lab. please take this into consideration when you perform an experiment as i would hate for somones else to have to go through this traumatic ordeal i have experienced.
What are the indicators that can be used to determine dissociation constant?
If you mean chemical indicators as used for indicating pH and reaction end-points, the answer is none, unless you are only looking for a very rough estimate at dissociation constant. The error involved in using an indicator would be very large. If you used an indicator, choice would depend on the compound, what its dissociation constant was and what it dissociated to.
Where to find universal adapters ?
If you go on amazon you can find a universal adapter that costs very low. It is a quick and efficient way to get one. You can even look for one that has free shipping.
What is the name of the chemical which changes colour when it is mixed with acids or alkalis?
If you want the general term, it's "indicator". If you want a specific one ... methyl red, litmus, or bromothymol blue are some examples (there are lots of others).
What force only works on the microscopic scale?
The four forces are:gravity - very long range and always attractiveelectromagnetic - long rangeweak nuclear force - very short range, limited to atomic nucleusstrong nuclear force - very short range, limited to atomic nucleus
Why is the universal indicator more useful than the red cabbage?
The universal indicator is better than the red cabbage indicator because the universal indicator has a wider range of pH that it can explain why a substance is acidic or basic. The red cabbage indicator only tests the substance if it is an acid or a base. Also, the universal indicators are made carefully and it is manufactured in a precise manner so the results are very reliable. Red cabbage indicators will vary in concentration which could cause errors to occur in determining the pH of a substance.
Will strong acids turn universal indicator paper purple?
The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.
Why is a universal indicator better than a litmus?
coz universal indicator tells you whether its a strong or weak acid or alkali but litmus paper only tells you whether the sunstance is acid (red) or alkali (blue)
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 colour would baking soda turn on a universal indicator?
Teal. Very grainy substance, hard to stir.I did a lab on it, trust.:)*Note: The indicator must be a high reddishorange (high acid, stains clothing) in orderfor it to work!Hope this helped!
How do you make a universal indicator?
Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
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 colour does acid rain turn universal indicator?
It should turn the UI to a light yellow because it is a very mild acid. It has a pH level of around 6. Whereas a strong acid like Battery Acid (pH 1) would make it a red.
What color is nitric acid on the universal indicator?
The colour of nitric acid on the universal indicator is red.In the event you work around nitric acid, please heed these warnings: STRONG OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE. CORROSIVE. LIQUID AND MIST CAUSE SEVERE BURNS TO ALL BODY TISSUE. MAY BE FATAL IF SWALLOWED OR INHALED. INHALATION MAY CAUSE LUNG AND TOOTH DAMAGE.
Does the pH of the soil affect the colour of flowers?
Yes it does. In some flowers, they act like Universal Indicator. (universal indicator goes blue if its very basic- also known as alkaline- and it goes red if something is acidic) So some flowers go red in acidic soil, and change to blue if the soil goes basic.
What turns hydrochloric acid red?
Hydrochloric acid itself is a colorless solution. However, it can turn red when it is in contact with certain chemicals or impurities that might be present in the environment. The red color typically indicates a reaction or contamination rather than a natural property of hydrochloric acid.
What coluor would a wasp sting go if you added universal indicator?
Most wasp stings have a neutral pH, around 7. If a wasp sting was added to a universal indicator, it would turn a shade of green. Also tern is actually spelt turn
