an acid, base, or salt
Most compounds that produce an electrolyte in aqueous solution are ionic. When dissolved in water, ionic compounds such as salts dissociate into their constituent ions, increasing the solution's conductivity, which allows it to conduct electricity. This is why most electrolytes in aqueous solution are ionic compounds.
Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.
dissociating into their component ions when they are dissolved in water. This process separates the positively and negatively charged ions, allowing them to move freely in the solution.
Compounds that produce hydroxide ions in solution are called bases. Some common examples include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). When dissolved in water, these compounds release hydroxide ions (OH-) which can react with acids to form water and a salt in a neutralization reaction.
Covalent compounds do not undergo electrolysis because they do not dissociate into ions in solution to conduct electricity. In order for electrolysis to occur, there needs to be free-moving ions in the solution to carry the current. Covalent compounds remain as intact molecules with strong bonding, so they do not produce the necessary ions for electrolysis.

There are no free charged particles to carry charge (apart from graphite, in which carbon atoms have non-bonding electrons which can carry charge). Metallic substances have free electrons and in ionic compounds the ions themselves are charged and can carry charge if they can move, hence ionic compounds can conduct when molten or in solution.
A base in solution will produce hydroxide or OH- ions.
An electrical current can pass through a solution of dissolved ionic compounds because the compounds dissociate into ions, which allows for the movement of charged particles (ions) in the solution. These ions carry the electric charge and enable the conduction of electricity through the solution.
Hydroxide (OH-) ions
All acids produce hydrogen ions (H+) in aqueous solution.
