Carbonates of metals typically exhibit thermal stability, breaking down upon heating to release carbon dioxide and form metal oxides. They are often ionic compounds, with metal cations bonded to carbonate anions (CO3²⁻). Solubility varies widely among different metal carbonates; for instance, alkali metal carbonates are generally soluble in water, while many transition metal carbonates are insoluble. Additionally, metal carbonates can react with acids to produce carbon dioxide gas, water, and corresponding metal salts.
When carbonates react with hydrochloric acid, the salt produced is a metal chloride, carbon dioxide gas, and water. The specific metal chloride salt formed will depend on the metal cation in the carbonate compound.
stupididity lol hehe
Carbon dioxide can react with some metals, like magnesium or lithium, to form metal carbonates. In the presence of moisture, carbon dioxide can also corrode metal surfaces, leading to the formation of metal carbonates or metal oxides. Additionally, carbon dioxide can react with metal compounds, such as metal hydroxides, to form metal carbonates through a neutralization reaction.
The carbonates of the metals in group I reacts easily.
· Examples of metal carbonates
Both metal carbonates and metal hydrogen carbonates form carbon dioxide when mixed with acid.

No, carbonates do not contain silicon. Carbonates are composed of carbon and oxygen, typically combined with a metal such as calcium, magnesium, or iron. Silicon is a separate element found in silicate minerals.
Yes; for example soluble carbonates.
Bases are substances that react with acids and neutralize them. They are usually metal oxides, metal hydroxides, metal carbonates or metal hydrogen carbonates. Many bases are insoluble - they do not dissolve in water.If a base does dissolve in water, we call it an alkali.
Yes, metallic carbonates are basic compounds. When they dissolve in water, they release hydroxide ions, which can react with acids to form salts and water.
