Examples are: silver chloride, cadmium sulfide, calcium carbonate, barium sulfate etc.
Only some salts are insoluble.
This is not mandatory: some salts are very soluble, some salts are very insoluble.
Some hydroxides are soluble, some are insolubles.
Insoluble salts are typically formed by mixing two solutions of soluble salts that contain ions that react to form an insoluble compound. This compound then precipitates out of solution, forming the insoluble salt. Methods to create insoluble salts include precipitation reactions and double displacement reactions.
Some are soluble (NaCl), some are insoluble (AgCl).
Insoluble salts can be made by combining a solution of two soluble salts that contain ions which form a sparingly soluble compound when combined. The insoluble salt will then precipitate out of the solution. This process is often used in a lab setting to create insoluble compounds for further testing or analysis.
Some salts are insoluble in water. All types of sodium chloride are soluble in water.
The preparation of insoluble salt can be done by PRECIPITATION METHOD
Some chlorides are soluble (NaCl), some chlorides are insoluble (AgCl) in water.
Insoluble salts can be prepared by mixing solutions of two soluble salts that react to form the insoluble salt through a precipitation reaction. Another method is to react a soluble salt with a soluble base or acid to form the insoluble salt. Alternatively, you can mix two solutions of soluble salts that have a common ion to reduce solubility and form the insoluble salt.
You could maybe put it in hot water like on a pan with hot water then boil it
Salts may be soluble or insoluble in water.
