What is carbonate in simple words?
A carbonate is a chemical compound that has the carbonate ion, CO 2− 3. . This ion is made of carbon and oxygen. The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O–)2 of carbon and oxygen.
What is meant by carbonate and bicarbonate?
Carbonates and bicarbonates are salts of carbonic acid. They are polyatomic ions (containing two or more atoms).
What is the use of carbonate?
The main uses of carbonates is as raw materials in different industrial processes such as drug development, glass making, pulp and paper industry, sodium chemicals (silicates), soap and detergent production, paper industry, water softener, clay and concrete production, among others.
Which carbonate is the most stable?
The stability of the alkaline earth metal carbonates increases as the basic character of their hydroxides increases down the group since Ba(OH)2 is most basic, therefore,BaCO3 is most stable.

What is carbonate found in?
Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years.
Is carbon and carbonate the same thing?
As nouns the difference between carbonate and carbon
is that carbonate is any salt or ester of carbonic acid while carbon is (uncountable) the chemical element (symbol c) with an atomic number of 6.
What is repartee conversation?

What does the German word zeitgeist mean?
In German, such a spirit is known as “Zeitgeist,” from the German words Zeit, meaning “time,” and Geist, meaning “spirit” or “ghost.” Some writers and artists assert that the true zeitgeist of an era cannot be known until it is over, and several have declared that only artists or philosophers can adequately explain it.
Is a carbonate a base?
Carbonates are moderately strong bases. Aqueous solutions are basic because the carbonate anion can accept a hydrogen ion from water. CO32− + H2O ⇌ HCO3− + OH− Carbonates react with acids, forming salts of the metal, gaseous carbon dioxide, and water.
How is carbonate formed?
Carbonates are the salts of carbonic acids. They form when a positively charged metal ion comes into contact with the oxygen atoms of the carbonate ion. These compounds are often insoluble in water and exhibit some level of basicity or acidity in aqueous solutions.
What does carbonate mean in science?
Carbonate, any member of two classes of chemical compounds derived from carbonic acid or carbon dioxide (q.v.). … Inorganic carbonates comprise many minerals (see carbonate mineral) and are the principal constituents of limestones and dolomites; they also comprise the hard parts of many marine invertebrates.
How do you identify a carbonate?
Carbonates can be identified by:
- Mix in a dilute acid.
- Collect the gas formed.
- Bubble the gas through lime water.
- If a white precipitate forms, carbonates were present.
Is siderite a carbonate ore?
The carbonate ore of iron is known as Siderite.
What is the common name for calcium carbonate?
Calcium carbonate (also known as chalk), mined as calcite, is the most commonly used filler for PVC.
Which metal carbonate is hardest to decompose?
This means that sodium carbonate is very stable and requires a high temperature to decompose. However, copper is a very unreactive metal, which is why it is useful for making water pipes, and so copper(II) carbonate is quite unstable and decomposes at a relatively low temperature.
Which one is the most stable carbonate a BaCO3?
BaCO3 is more thermally stable because polarising power of Ba2+ is less than other alkaline earth metals and thermal stability is inversely proportional to polarising power of action when compound containing polyatomic anion and here carbonate is polyatomic anion.
Which is least thermally stable?
BeCO3 is least thermally stable. The thermal stability of carbonates increases down the group i.e from Be to Ba.
Why is calcium carbonate bad for you?
Calcium supplements may increase the incidence of constipation, severe diarrhea, and abdominal pain. It highlights that calcium carbonate is more often associated with gastrointestinal side effects, including constipation, flatulence, and bloating.
Is it OK to take calcium carbonate daily?
For all women and men over 65, daily intake is recommended to be 1,500 mg/day, although further research is needed in this age group. Calcium intake, up to a total intake of 2,000 mg/day, appears to be safe in most individuals.
What are the four uses of calcium carbonate?
Calcium carbonate is an important ingredient of many household products. It is used as a whitening agent in paints, soaps, art products, paper, polishes, putty products and cement.
