Can you freeze yourself solid and live?
Only for a very, very short period of time.
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 is the weather like in England year round?
Very varied is the only short answer.
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.
How water is known as universal solvent eventhough it doesnt dissolve all substances?
Water is a very good and known solvent but it is not an universal solvent. An universal solvent doesn't exist and is absolutely impossible to obtain an universal solvent.
What turns hydrochloric acid red?
Universal indicator. HCl has a very low pH, which means it is very acidic and will turn universal indicator red or orange.
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.
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.
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.
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.
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)
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 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).
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 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
What color does Universal indicator turn in diluted hydrochloric acid?
Hydrochloric Acid is known to be a very strong acid. A 0.01 molar solution of HCl has a pH of 2 ( -log(0.01) ) which on the pH scale is very acidic (under 7 is acidic, 7 is neutral, over 7 is basic). On a universal indicator test, HCl would come out as red. A basic solution would be a more blue-green, or green depending on the concentration.This is a color chart for a universal indicator test:http://chem.csusb.edu/images/pH_chart.gif
Was he really only very short?
yes
