For example, can Cu2+ be the only ionic species present in an aqeuous solution, without anions such as nitrate. (Hydroxide ions ignored)
Can a solution contain only cations?

In summary, it is not possible for Cu2+ to be the only ionic species in an aqueous solution without any anions present. Solutions must always be electrically neutral and even small drops with a slight charge will eventually discharge. It is not recommended to attempt to create a solution with only cations present.

No, solutions are always electrically neutral.
That is, it is possible for a small drop to have a small charge, but nothing close to bulk solution containing only cations or only anions. Just like any charged object it will discharge at first occasion.

FAQ: Can a solution contain only cations?
Can a solution contain only cations?
Yes, a solution can contain only cations. This type of solution is called a cationic solution and it is a type of electrolyte solution that contains positively charged ions. It is commonly used in various industrial, medical, and research applications.
What are cations?
Cations are positively charged ions that are formed when an atom or molecule loses one or more electrons. They are attracted to the negative electrode, or cathode, in an electrolytic cell and are essential for many chemical reactions and processes.
How are cations different from anions?
Cations are positively charged ions, while anions are negatively charged ions. Cations are formed when an atom or molecule loses one or more electrons, while anions are formed when an atom or molecule gains one or more electrons. In a solution, cations and anions are attracted to each other and balance each other out.
What are the properties of cations?
Cations have several important properties, including their charge, size, and reactivity. The charge of a cation depends on the number of electrons it has lost, while its size depends on the number of protons in its nucleus. Cations can also react with other ions and molecules to form compounds and participate in various chemical reactions.
Can cations be toxic?
Yes, some cations can be toxic to humans and other living organisms if ingested in large quantities. Examples of toxic cations include lead, mercury, and cadmium. These cations can disrupt biological processes and cause harm to the body. However, many cations are essential for proper bodily functions and are not harmful in small amounts.
