Why are precipitate and gas evolution reactions irreversible ( why don't the products react once again ) ??
What if the products were to be produced in a closed vessel ?Yanick said:Because they are no longer available for reacting. Assuming the gas has very little solubility in the solution, once it forms it will bubble out and diffuse into the atmosphere.
Yanick said:The precipitate is a bit trickier but not really. When a solution is in contact with a precipitate the interaction between solvent (or whatever solutes may be present) and the solid occurs at the interface of the phases. That is only the exposed layer of solid will ever get to see the solvent or solutes. You can demonstrate this to yourself by dissolving equal masses of sugar in water but using sugar cubes versus confectioner's sugar (or regular powdered sugar, or all three). You'll quickly notice the different behaviors and should be able to relate this back to your situation.

An irreversible precipitate is a solid substance that is formed when two or more chemical reactants are combined. Unlike a reversible precipitate, which can be dissolved or separated back into its original components, an irreversible precipitate cannot be easily reversed.
Gas evolution is the process by which a gas is produced during a chemical reaction. This can happen when two reactants combine to form a gas as a product, or when a reactant breaks down into smaller molecules, some of which are gases.
The formation of an irreversible precipitate can be influenced by a variety of factors such as reactant concentrations, temperature, and the presence of a catalyst. The solubility of the reactants and products also plays a role in the formation of a precipitate.
Yes, there can be safety concerns when dealing with reactions involving irreversible precipitates and gas evolution. Some of the reactants or products may be toxic, corrosive, or flammable. It is important to follow proper safety protocols and handle these reactions with caution.
Yes, it is possible for an irreversible precipitate and gas evolution to occur simultaneously in a chemical reaction. This can happen when a reactant decomposes into both a solid precipitate and a gas as products. It is also possible for a reversible precipitate to form initially, which then undergoes further chemical reactions to become an irreversible precipitate while also producing gas as a product.
