can the reaction between alkali and acid be reversed
Chemical changes that involve physical changes, such as melting, boiling, or dissolving, are generally reversible. Reactions involving phase changes or reversible reactions where products can revert back to reactants under certain conditions are reversible. An example is the reaction between water and carbon dioxide to form carbonic acid, which can decompose back into water and carbon dioxide.
A double arrow in a chemical equation represents a reversible reaction, meaning that the reaction can occur in both the forward and reverse directions. It signifies that the reaction can reach equilibrium where the rate of the forward reaction equals the rate of the reverse reaction.
4nh3 + 5o2 --> 4no + 6h2o
The process of boiling water and cooling the resulting water vapor is reversible because it can be easily reversed by either heating the cooled water or condensing the water vapor. When water is boiled, it turns into vapor due to the input of heat energy. Conversely, when the water vapor is cooled, it condenses back into liquid water by releasing heat energy.
The reaction between formaldehyde and sulfuric acid forms methylene bisulfate. This is a reversible reaction that can also produce bisulfite ions and water as byproducts.
Phenolic resin is made by the reaction between phenol and formaldehyde, whereas urea formaldehyde resin is made by the reaction between urea and formaldehyde. Phenolic resin offers higher heat resistance and better moisture resistance compared to urea formaldehyde resin. Urea formaldehyde resin is typically more cost-effective and has better flexibility than phenolic resin.
A change in which the products are the same as the reactants is called a reversible reaction or an equilibrium reaction. This means that the reaction can proceed in both the forward and reverse directions, resulting in a dynamic balance between reactants and products.
Reversible reactions never complete because they reach a state of dynamic equilibrium, where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that products are constantly being converted back into reactants and vice versa, preventing the reaction from reaching completion.
The reactions in which the products can recombine to form reactants are called reversible reactions. These reactions never go to completion. They are represented by a double arrow between reactants and products.
This type of reaction is known as a synthesis reaction, where two reactants combine to form a single product.
Urotropine synthesis involves the reaction of formaldehyde with ammonia at elevated temperatures. This process forms hexamethylenetetramine, also known as urotropine, through a series of condensation reactions. The reaction typically occurs under acidic conditions to facilitate the formation of the desired product.

There is no reaction between these two substances because an exchange of positive ions wouldn't result in higher product stability. Make sure your not confusing acetic with ascetic.
