Why can ammonium carbonate be used to identify both acidic and alkaline solutions?
Soullesstoasters
It can identify acids and alkalis because it reacts with both.
If you add some crystals of this to acid carbon dioxide gas will bubble up, and this turns lime water milky.
If you add some crystals to an alkali, ammonia smell will be recognised. A more stringent test is that it turns damp litmus paper blue.

Who discovered Ammonium Chloride?
No one is certain who first discovered Ammonium Chloride as reference to it dates back to ancient scholars. However, no one knew the actual chemical composition until it was discovered by Joseph Tournefort in 1700.
How is a mineral acid test used to identify minerals?
Dilute acid or vinegar is placed on the specimen to see if it effervesces or reacts. If it instantly reacts it is probably a carbonate mineral like calcite. Other minerals may slowly dissove in the acid. Some minerals have no reaction to the acid.
Does sodium carbonate react with alcohols?
Yes, the sodium carbonate will react with ethanoic acid. You will be able to see a weak bubbling to signify the reaction.
Least accurate way to identify a mineral?
the least accurate way to identify a mineral
What is the name of the scale we use to identify minerals?
the mohs scale is the scale we use to identify minerals
How can you identify Ammonium?
Ti identify ammonium ion, NaOH is added to the original solution of the ammonium salt and a paper dipped in HCl is brought to mouth of test tube. If white vapours are observed, then ammonium is present. Or Neissler's reagent(K2HgI4) can be added to the original solution of the ammonium salt. A reddish brown ppt. is observed in case of ammonium ion.
How do you identify if two solutions are isotonic?
The two solutions are then the same strength.

What unique properties will help you identify the soluble compound as either sodium carbonate or starch?
Sodium carbonate is soluble in water
How do you identify the chloride ion that is present in solid ammonium chloride?
- Dissolve ammonium chloride in water.- Add some crystals of silver nitrate and stir.- A white precipitate of silver chloride is formed.
How could you use sodium carbonate powder to identify the solution that contains acid?
No I cannot answer it! Hahahahahahahahahaha!
How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
What type of test can be used to identify calcium carbonate?
add hcl bubbles of co2 produced and flame test
Why is there a need to identify as many possible solutions to a problem?
Certain solutions identified at certain points of time will not be suitable at a later point of time, hence it is better to have as many possible solutions to a problem.
Explain how to identify whether an equation has no solution or infinitely many solutions?
An equation can be determine to have no solution or infinitely many solutions by using the square rule.
How do you identify insoluble and soluble solutions?
This question needs to reworded, it makes no sense as written. Perhaps the question is supposed to be "how do you identify soluble and insoluble salts"?
Would it be possible to identify chloride iodide carbonate sulfate if mixed together?
By using specific methods of analytical chemistry.
