What is the solubility of carbonate salts?
Some carbonates are soluble (carbonates of alkali metals) and some carbonates are practically insoluble in water (calcium and magnesium carbonate etc.).
Why carbonate salts are insoluble?
Not true; as an example all the alkali carbonates are very soluble in water.
Compare and contrast the preparation of a salt from an alkali and a base?
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.
Is all carbonate dissolve in water?
Chemically most carbonates are insoluble (Do not dissolve in water). The exception are the carbonates of Group(I) Alkali metals e.g. Sodium. Similarly, most sulphates. However, Chlorides and nitrates are soluble.
Is aluminum an alkali metal?
These carbonates have the formula Me2CO3; for bicarbonates MeHCO3.
How much KVAr capacitor is needed for 2500KVA transformer?
Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions).
What do you get when acids react with carbonates?
alkali
What is the solubility of carbonate salts?

Why does the use of aluminum containers interupt the saponification process, and what material would completely prevent the saponification process?
Saponification is a process of converting esters into soaps and alcohols by the action of aqueous alkali (for example, aqueous sodium hydroxide solutions).
Are common carbonates soluble?
Carbonates are generally not very soluble in water, though their solubility increases considerably if the water is even slightly acidic. The alkali metal carbonates are soluble.
What is an aqueous solution of a base called?
An alkali.
Which carbonates do not produce CO2 and why?
The carbonates of alkali metals (Ist group) do not evolve CO2 on heating because their oxides are highly unstable.
Is petrol acid or alkalis?
None of it. It is an oily substance, not a watery solution like acid and alkaline are. Petrol is a hydrocarbon and is not soluble in aqueous solutions of acids or alkalis.
Why is there a temperature changes when alkali is added to vinegar?
When an alkali (base) is added to vinegar, the acetic acid in the vinegar reacts with the alkali. These reactions are nearly all exothermic, that is, they generate heat as the chemical reaction proceeds. This is observed by a change in the temperature of the aqueous solution and the surrounding air.
When an acid reacts to an alkali is the compound neutralisation?
The process of equalising the concentrations of OH- and H3O+ in an aqueous solution by reacting an acid and an alkali together, via the reaction OH- + H3O+ ---> 2H2O.
Why carbonate salts are insoluble?
Not true; as an example all the alkali carbonates are very soluble in water.
Does acid produce a gas with an alkali?
No gas is produced in the reaction of an acid and an alkali. In a neutralisation reaction, acid + alkali -> salt + water
