Final answer:
To displace a base from a salt, one can add an acid which reacts with the salt to release the base, or perform a single displacement reaction, like adding zinc to copper sulfate,
Step-by-step explanation:
To displace the base from the salt, one can perform a chemical reaction where an acid reacts with the salt, causing the base component to be released. For instance, if we take the example of sodium carbonate, a common salt, and add hydrochloric acid to it, a reaction ensues producing carbon dioxide, water, and sodium chloride.
This is an example of an acid-base reaction where the acid (hydrochloric acid) displaces the base (carbonate) from the salt (sodium carbonate).
In another scenario, we can displace a metal from a salt solution through a single displacement reaction. As demonstrated in a laboratory experiment, placing zinc metal into a copper sulfate solution will result in zinc displacing the copper from the solution to form zinc sulfate, with copper metal being deposited.
These processes align with the concept that salt solutions can undergo ionic dissociation, where salts like sodium chloride dissolve in water disassociating into their respective ions.
Chemical reactions that involve the dissolution or displacement of bases from salts leverage this ionization property and depend on the reactivity of the components involved.
