Which of the following methods is suitable for preparing insoluble salts?
Answer Details
The method suitable for preparing insoluble salts is double decomposition.
Double decomposition is a chemical reaction in which two ionic compounds exchange ions to form two new compounds. This reaction can occur when one of the products is insoluble in water, leading to the formation of an insoluble salt.
In the process of double decomposition, the cations of one compound switch places with the cations of the other compound, resulting in the formation of two new compounds. If one of these new compounds is insoluble in water, it will precipitate out of the solution as a solid. The insoluble compound can then be collected through filtration and washed with water to remove any remaining soluble impurities.
Thermal decomposition involves breaking down a compound into simpler substances by heating it. Oxidation involves adding oxygen or removing hydrogen from a compound. Neutralization is a reaction between an acid and a base to form a salt and water. These methods are not suitable for preparing insoluble salts.
Therefore, double decomposition is the suitable method for preparing insoluble salts.
