Why can ammonium carbonate be used to identify both acidic and alkaline solutions?
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.
When dilute hydrochloric acid is placed on the sedimentary rock limestone and the metamorphic rock marble bubbling reaction occurs with both What would this indicate?
The bubbling reaction indicates that both limestone and marble contain calcium carbonate. The hydrochloric acid reacts with the calcium carbonate to produce carbon dioxide gas, which is seen as bubbles. This is a common test to identify rocks containing calcium carbonate.
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.
Which sedimentary rock would react with hydrochloric acid?
Limestone for sure, dolomite mildly.
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.
What unique properties will help you identify the soluble compound as either sodium carbonate or starch?
Sodium carbonate is soluble in water
How could you use sodium carbonate powder to identify the solution that contains acid?
Adding sodium carbonate powder to an acid solution will cause fizzing or effervescence due to the reaction of the acid with the carbonate. This can help identify the presence of an acid in the solution.
What is a chemical property that can be used it identify calcium carbonate?
One chemical property that can be used to identify calcium carbonate is its reaction with hydrochloric acid to produce carbon dioxide gas, which causes effervescence. Additionally, calcium carbonate will turn a solution of calcium hydroxide milky when added, indicating the presence of carbonate ions.
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.
What minerals will fizz in contact with hydrochloride acid?
Minerals containing carbonate ions, such as calcite (calcium carbonate) and dolomite (magnesium carbonate), will fizz in contact with hydrochloric acid due to the release of carbon dioxide gas. This reaction is a common test to identify carbonate minerals.
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.
A scientist suspect that a mineral sample is a carbonate. which useful for identifying the sample as a carbonate?
To identify the mineral sample as a carbonate, the scientist can perform an acid test. If the sample fizzes or produces bubbles when acid is added, it indicates the presence of carbonate minerals. Additionally, spectroscopic analysis can be used to detect the specific chemical composition of the mineral, confirming its classification as a carbonate.
What does the acid test tell you about a mineral?
The acid test is used to determine if a mineral contains carbonate minerals. When a mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite. This test helps mineralogists identify and distinguish between different minerals.
What happens when you add ammonium with sodium Hydroxide?
When you add ammonium (NH4^+) with sodium hydroxide (NaOH), it forms ammonia (NH3) gas, water (H2O), and sodium chloride (NaCl) salt through a reaction called neutralization. This reaction can release heat, and can be used to identify the presence of ammonium ions in a solution.
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 minerals will bubble when treated with hydrochloric acid?
Minerals containing carbonate ions, such as calcite (calcium carbonate) and dolomite (calcium magnesium carbonate), will bubble when treated with hydrochloric acid due to the release of carbon dioxide gas. This reaction is a common test to identify the presence of carbonate minerals in rock samples.
